A senior police sergeant in Samoa has lost his job after he was convicted and sentenced to five months in jail for official corruption.

Two constables have been discharged without conviction after they pleaded guilty to charges of being an accessory after the fact and conspiracy to defeat the cause of justice.

The senior officer, Antonio Tausili, was the supervisor at Faleata police post in December 2013 when the two constables attended a call from a family at Vaitale who needed assistance over a family commotion.

The officers, Heta Wilson and Luisa Lototau, found two cannabis joints on one of the family members, but Tausili told Wilson not to take the narcotics back to the police post.

They were later flushed down the toilet by Lototau.

The police in Samoa have started the New Year with a drug raid on family land at Safaato'a village in which two suspects have been arrested, including a woman. However, one man had escaped at the time of the police raid on Friday afternoon. Police say fifty seven cannabis, or marijuana plants, from six to seven feet high, were found growing on the family land. Hundreds of dried leaves were also found along with live ammunition, and the police suspect guns were also part of the illegal drug operation. No street value of the found cannabis was given, but the police have thanked the people of Safaato'a village for their support and they urge other villages to follow suit in reporting illegal drugs.
