LITTLE ROCK, Ark. (AP) - A federal judge has granted a request to postpone the trial of two former Little Rock police officers facing drug-related charges.

Court records show that half-brothers Mark Anthony Jones and Randall Tremayn Robinson are now slated to go on trial March 18. Jones and Robinson were previously scheduled to go on trial starting Monday.

Jones and Robinson were arrested in May and have since been released.

Prosecutors say they drove marked patrol cars while protecting controlled drug deliveries.

They have both pleaded not guilty to drug-related charges.

Robinson resigned from the police department and Jones was fired.
