He was produced in court and remanded till May 26.
Senanayake was arrested after being questioned earlier in the day and was accused of concealing evidence when he was involved in the investigations.
He was questioned previously as well in connection to the controversial case.
Earlier this month the police DIG in charge of motor traffic Amarasiri Senaratne was also questioned by the CID over Thajudeen’s murder.
The Colombo Additional Magistrate in February ordered the CID to arrest the suspects linked to Thajudeen’s murder.
Thajudeen died on May 17, 2012 in Kirulapone and his body was found in his car which had crashed into a wall.
According to police reports in 2012, the rugby player was driving home after attending a party when he lost control of the car and crashed into a wall on Park Road.
The police claimed that the car had exploded instantly and burnt the victim.
However suspicions later arose over the manner in which he died and it was believed that he was murdered. (Colombo Gazette)
