Sri Lanka's former ambassador to Russia, Udayanga Weeratunga has been further remanded till 26 February by the Fort Magistrate's Court.

Weeratunga was questioned by the CID at the Katunaike Bandaranaike International Airport upon his arrival to Sri Lanka last week. He was later taken into custody.

Weeratunga was under investigation for several high-profile cases including the MIG deal.

Weeratunga, a close relative of the Rajapaksa family, returned to the country after evading arrest for nearly two years.

Although an Interpol warrant was issued on him, the Police could not take measures to arrest the former Ambassador.
