The Trinidad Guardian reported that a group of four lawyers arrived at the station and spent around 45 minutes before exiting and speaking to the media. While being interviewed by reporters, the attorneys were called by police.
They went into the building and when they excited, they quickly left the scene.
The investigations reportedly relate to witness tampering allegations levelled against Ramlogan by Police Complaint Authority (PCA) director David West two years ago.
West had alleged that Ramlogan called him days before his appointment to the PCA and asked him to withdraw as a witness in a matter involving then Opposition Leader Dr Keith Rowley.
Ramlogan has vehemently denied the allegation.
However, Acting Police Commissioner Stephen Williams launched investigations into the matter in January 2015.
Several former government officials under the People’s Partnership administration led by Kamla Persad Bissessar have already been questioned by police in the high profile case.
They include former National Security Minister Gary Griffith, former Legal Affairs Minister Prakash Ramadhar, former Minister in the Ministry of Finance Vasant Bharath, and former Housing Minister Dr Roodal Moonilal. Former Trinidad Express investigative journalist Anika Gumbs who broke the story in January 2015 was also questioned.
