Bengaluru: The Bengaluru Central Crime Branch (CCB) officials arrested a Congo national named David Bosa on Saturday night when he was trying to sell cocaine. The police said they found 8 gram of the banned drug worth 80,000 and have seized it.

According to assistant commissioner of police (ACP), CCB, Mohan Kumar, the accused Bosa Lukengo Dayve alias David Bosa aged 28 had come to Bengaluru some seven years ago and after graduation in 2016, he is staying illegally.

"The accused has no records of such an offence in the past, we have sent him to judicial custody now," said Kumar.

The officer said African nationals like Bosa and some others in the past were caught for offences like possessing and selling banned drugs, online scam or for sex racket. And they have established their own network to illegal business. Many of them have their visas expired, he said.

"The accused find one or the other way to stay in India, especially in Bengaluru. Hence they get caught in offences and get an FIR registered and by the time the trial finishes, it takes at least five years," said a senior officer.

According to police sources, African nationals who come on student or work visa prefer to stay in Bengaluru's east zone like Byrathi, Kothnur, KR Puram, Banaswadi, Hennur as rented houses are affordable and also find educational institutions that admit them.
