A Prince George’s County police officer who already faced charges in a cocaine trafficking conspiracy was accused Monday of participating in a scheme to distribute black market cigarettes and liquor.

Sinisa Simic, 25, who joined the force in 2007, was indicted Monday in U.S. District Court in Greenbelt on charges of conspiracy to commit extortion and weapons violations. Federal authorities allege that Simic was paid to use his authority as a police officer to help transport untaxed cigarettes in Maryland and Virginia.

Federal authorities have said the allegations of liquor and cigarette trafficking are part of a far-reaching corruption probe in Prince George’s County. The investigation became public in November when former County Executive Jack B. Johnson (D) and his wife, Leslie, were arrested and accused of evidence tampering in a bribery investigation.

Simic is accused of working with another man, Mirza Kujundzic, 30, of Woodbridge. Kujundzic also was indicted Monday on conspiracy charges.

A Prince George’s County Police spokesman said Simic is on leave without pay pending the outcome of the criminal case.
