Two day Eid-ul-Adha in Karnataka; public holiday on Sept 13

Mangaluru, Jan 10: Two members of a notorious honey-trap gang that used to lure rich men using women and then extort money from them by staging fake police raid have been arrested by the Dakshina Kannada district police.

Lohith, a resident of Kushalnagara, and Sharif from Vittal, were arrested in connection with a honey-trap case registered in Uppinangady police station. Jamal, Jeevan and Naushad, who were also involved in the case, are absconding.

Police said they received information that a few people under the guise of being Kerala police, were planning to raid a resort near Uppinangady where two couples were staying.

They were informed that they would threaten and try to extort money from them. The police were tipped off about the same by their counterparts in Kerala.

Police said the accused are experts in setting honeytraps, and were involved in similar crimes since a long time. Their modus operandi was to use two women from Mangaluru to lure their intended targets.

Once they trap their target, the woman and victim are sent to resorts. They then raid the resort posing as police officials, and click pictures in compromising positions of the victim with the woman.

They threaten to release the pictures on social media or TV channels, if they fail to pay up.

Police said the accused demanded Rs 10 lakh from each victim, but they denied to pay up. Irked by this, the accused took away the victims’ belongings such as phone, money and car.

The victims who believed that the accused were police personnel, asked them to take them to the police station. Instead of taking them to the police, the accused took them to a secluded place, where they claimed that they were putting the victims under house arrest. Police have seized an SUV from the accused.

Mangaluru, Mar 30: Police on Monday registered a case against a man, who, after return from Dubai, had failed to adhere to lockdown guidelines of house quarantine.

The case was filed by Assistant Commissioner, Puttur, Dr Yathish Ullal.

The man, who returned from Dubai on March 21, had a seal on his hand and was supposed to stay at home for 14 days, but was seen roaming around the city, hence he was taken into custody and a case registered.

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study
