The Correctional Service Department has uncovered a plot to kill Kartel.
Kartel and three co-accused were convicted last year and sentenced to life imprisonment for the murder of Clive Lizard Williams.
According to well placed sources, prison personnel uncovered the plot to kill Kartel.
It reportedly involved an ancillary worker and a fellow inmate at the Horizon Adult Remand Centre.
According to our sources the ancillary worker confessed that she was directed by the inmate to pick up what was purported to be two bottles of lotion and three ratchet knives.
She managed to smuggle the items into the high-security institution. Following investigations the items were discovered in a section of the facility.
The ancillary worker was accosted and she later confessed to being involved in the plot to pass the items to the inmate who was allegedly planning to attack Kartel when both would be released from their cells.
The ancillary worker has been taken into custody and is expected to be further questioned.
