The call was made on Tuesday by Social Activist and Chairman of the Emancipation Support Committee, Khafra Kambon, who claimed there are medical and human rights violations at the Detention Centre.
He highlighted one case of a man who lost his hearing because of poor medical care after being beaten in the Detention Centre.
"There's a brother who was very violently beaten while in the Detention Centre and I think the press should investigate how many people the Detention Centre is built to hold and how many persons are there now. It is vastly overcrowded."
Mr. Kambon made the statement following a Special Inquiry held by the Immigration Division to give Cameroonian, Laurent Pret Souop, an opportunity to have his matter aired publicly - a first for the Division.
According to Mr. Souop's Attorney Farid Scoon, the Cameroon national overstayed his time but when he tried to leave the country, his ticket, passport and a letter signed by the National Security Minister granting him permission to leave the country were all seized and he was placed in the Detention Centre.
Mr. Scoon said even though his client was granted permission to fly out of Trinidad and Tobago, local Immigration authorities detained him and continues to hold him at the Detention Centre in Aripo.
"Our system is flawed, what happened today for example and this is why today, we are pleased that this is the first time, I think, in Trinidad and Tobago that there has been a public special inquiry into an immigration matter."
Mr. Scoon said Mr. Souop's case is far from an isolated one.
"We think that this is a frequent case. We have a case of a Jamaican in the Detention Centre now who has a Trinidad father who has been in Detention Centre for almost three years and he has a Trinidad father which means he is a citizen of Trinidad and Tobago."
They are calling on the Attorney General's Office and the Ministry of National Security to address the situation at the Immigration Division.
