A D.C. police officer was arrested yesterday on charges of attempting to bribe a public official, in connection with an alleged attempt to pay a robbery detective $700 to drop an investigation of armed robbery allegations against a Washington D.C. man.

Johnnie M. Allen Jr., 28, of Forest Heights, an eight-year veteran assigned to the First District, was released on his personal recognizance after a hearing in U.S. District Court.

Magistrate Patrick J. Attridge ordered Allen released pending a preliminary hearing in the case on July 15. Attridge said that Allen, if convicted of attempting to bribe a public official, could face a maximum of 15 years in prison and a fine of up to $20,000.

According to an affidavit filed in court by police internal affairs division Sgt. Ronald Fisher, a man told police that he had been robbed at gunpoint on May 31.

Two weeks later, according to the affidavit, Allen approached a robbery detective handling the case and offered him money to see that charges were not brought against the alleged robber. Assistant U.S. Attorney E. Thomas Roberts said at the hearing that the alleged offer from Allen to the detective was for $300.

On June 21, Allen met with the detective and allegedly gave him $700 to make certain that the robber was not charged, Fisher said in the affidavit. Sources close to the case said yesterday that the suspected robber is friend of Allen's.

Roberts told Attridge in court that prosecutors have evidence that Allen has used cocaine. Attridge ordered Allen, who was arrested yesterday morning, to report for narcotics testing periodically, to stay in the D.C. metropolitan area, and to be at home every evening by 11 p.m.
