Six narcotics officers in the Philadelphia Police Department have been transferred to other units following allegations from the District Attorney's office that their credibility is too compromised for them to participate in drug cases.

Philadelphia Police Commissioner Charles H. Ramsey said he transferred the officers Tuesday, but declined to comment on his reasons for doing so. Four were moved to Center City districts, one to the traffic unit, and the other to the South Detective division.

According to multiple sources, this week the District Attorney's Office informed Ramsey that the office would no longer prosecute cases involving the officers.

The officers have been the targets of numerous lawsuits and complaints alleging that they have provided false testimony in court and used excessive force during arrests, records show. Sources said the District Attorney's Office has also investigated some of the officers for allegedly stealing money or drugs on the job.

Tasha Jamerson, a spokeswoman for the District Attorney Seth Williams, declined to comment Wednesday.
