Ten people were arrested, and heroin and more than $15,000 in counterfeit money were seized, after officers chased drug suspects to a West Baltimore home Thursday morning, a police spokesman said.

The bust netted more than $22,000 in cash, including the counterfeit money, said Baltimore police spokesman Anthony Guglielmi. He refused to release the names of the suspects, saying that the U.S. Secret Service was involved and that the investigation is continuing.

About 6:45 a.m., members of the Central District operations squad saw a gold Pontiac Grand Prix, which they believed to be involved in drug activity, in the 600 block of McCulloh St.

When men and women were observed engaging in a suspected drug activity, the officers attempted a traffic stop and the vehicle sped off. Officers followed the car into the Western District, where its occupants ran into a home in the 2300 block of Avalon Ave. in the Parkview/Woodbrook neighborhood.

Guglielmi said the officers "observed drugs in plain view" and obtained a search-and-seizure warrant for the home. Inside, they found $22,245 in cash, $15,580 of which was counterfeit, he said. Officers also seized seven bags of heroin and a half-ounce of raw heroin.

Of the 10 people taken into custody, Guglielmi said three were on probation, but he declined to provide their names or the crimes with which they were charged.

A representative of the Secret Service said an agent had been assigned to work on the case after the discovery of the counterfeit money.

No federal charges had been filed in the case.
