A D.C. government employe and the operator of a private trash company were arrested yesterday on bribery charges in connection with illegal sales of city government lubricants.

Carlton Michael Ford, 36, a $26,353-a-year supervisor at the Department of Public Works maintenance warehouse at 1725 Fenwick St. NE, allegedly sold five 55-gallon drums of city government motor oil on June 28 to an undercover police officer posing as a buyer of stolen merchandise, according to a D.C. police arrest affidavit. The undercover officer allegedly paid Ford $300, which police said he split with another D.C. government employe. The second city employe was not charged.

Edmond Johnson, 70, the operator of Kenilworth Trash Co., was accused of purchasing more than $500 of city government hydraulic fluids and chemicals. On July 23, police said they observed a D.C. government employe deliver the goods to the offices of Johnson's company at 4214 Hunt Place NE. Three days later an employe of Johnson's firm gave the unidentified city employe an envelope containing $205, according to the police affidavit. Both men were charged with bribery, a felony, and face up to 15 years in prison and a fine.

D.C. police said that the arrests culminate a three-month investigation that began when police received allegations that Johnson was purchasing city government petroleum products. Police said they were assisted in the investigation by the FBI and the U.S. Attorney's office.

Ford has been a city employe since 1971 and is assigned to the public works department's fleet management administration, according to a department official.

A man who answered the phone yesterday at Kenilworth Trash said "there's nothing to say."

Police said the investigation is continuing. The charges against Johnson and Ford will next be presented to a federal grand jury, according to the U.S. attorney's Office.
