UP cop killed by saffron extremists was investigation officer in Akhlaq lynching case

Bengaluru, Jun 18: The Karnataka police has arrested a German national wanted for kidnapping and causing bodily harm to a person in his home country, an official said on Wednesday. The person was also found to be overstaying on an expired visa, which police said that it appeared that the visa had been tampered with to look more current.

"On receipt of credible information by the CID Interpol Division officers, the Red Corner Notice subject, the German national Alexander Bruno Wehnelt, was traced at Hulimangala village," a police official told media persons.

Hulimangala is on the outskirts of Bengaluru city.

Alexander, 55, escaped from Germany and took shelter in Bengaluru.

The Interpol Division of CBI NCB (Central Bureau of Intelligence, Narcotics Control Bureau) in New Delhi had communicated to the Interpol liaison officer in Karnataka's Criminal Investigation Department (CID) about Alexander, directing extensive search measures to trace the criminal at large.

The Narcotics Control Bureau of Wiesbaden in Germany was on the hunt for Wehnelt for the crimes he committed in 2015, and have finally found him five years later.

"A special team of officers was constituted by the CID - Interpol division under the supervision of ADGP (Additional Director General of Police) B. Dayananda and the Interpol liaison officer and efforts were made to trace the subject," said the official.

On Monday, the police received credible information leading to his arrest.

"It was learnt that his visa had expired in 2016 and he tried to show a visa which was issued in December 2019 which had expired on Saturday, June 13," said the official.

Prima facie, it appeared that Alexander had tampered with his visa and the police are probing on that front as well.

He was handed over to Hebbagodi Police Station in Bengaluru Urban, for his overstay and a criminal case has been registered against him, under the Foreigners Act.

Mysuru, Jan 11: City Police has intensified its search for a girl student who a displayed 'Free Kashmir' poster during a protest two days back.

According to police, a girl student displayed the poster carrying an anti-national message, during the protest organised by University of Mysore Researchers Association and other organisation on Wednesday to oppose the attack on the students and the teachers in Jawaharlal Nehru University in the National Capital. An officer said that as per the documents available, it appears that a girl student displayed the placard for a few minutes.

"We are looking for the accused". The Jayalakshmipuram police have taken up suo motu cognisance of the case. Meanwhile. the office of Governor Vajubhai Vala, on Thursday, sought a detailed report from the University of Mysore (UoM) over the incident. The city police have booked the protestors under Section 124A of the Indian Penal Code (IPC).

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
