More than 75 law enforcement officers attached to various units within the T&T Police Service and Defence Force descended upon the Carapo mosque last night.
Police sources say among those held in the raid around 7 p.m. was Rajaee Ali, son of the north-west leader of the Jamaat-al-Muslimeen, Imam Hassan Ali.
Sources told the Express that Ali and several other men were praying in the mosque when officers announced their presence.
Sources say the officers said they were in possession of a warrant to search the compound. A search was conducted and sources say the men along with Ali were taken to the Arima Police Station for questioning. They remained in custody up to press time last night.
Following the raid, a high level de-briefing was held among senior officers in the Eastern division at the Arima police station. Calls to several of these officers in an effort to get comments were unsuccessful.
Ali is one of the co-ordinators of the controversial LifeSport programme.
The programme is currently being audited by the Ministry of Finance and the findings are expected to be handed over later this week.
Throughout a series of investigative articles by the Express, it was discovered that Ali was in charge of millions of dollars targeted for the programme.
In a previous interview with the Express, Ali admitted that police had detained him for gang-related activities following the murder of former independent senator and senior counsel Dana Seetahal. In that interview, Ali said he did not kill the former attorney.
