Six people including underworld gangster Kanjipani Imran's brother and father have been arrested for attempting to give him two mobile phones and chargers concealed in a lunch box at the Boossa Prison.

Imran has been sentenced to six years rigorous imprisonment for possessing and smuggling 5.3 kilograms of cannabis after he pleaded guilty to the charges.

He is also under investigation in connection with several other allegations.

Imran is believed to be a close associate of drug kingpin Makandure Madhush who was arrested in Dubai earlier this year. Both of them were arrested when the Police raided a party at a super-luxury hotel in Dubai.

The two gangsters were then extradited to Sri Lanka. They were arrested by the CID minutes after they landed at the Katunaike Bandaranaike International Airport.
