UPPER DARBY, Pa. (CBS) — A four-month undercover investigation of street-level drug sales in Upper Darby has resulted in ten arrest warrants.

Police have seven of those people in custody, and the search continued for the remaining three (in top photos).

Authorities set up shop on street corners near Chestnut Street and Garrett Road, about a block from the Upper Darby Municipal Building, after receiving complaints from residents about drug sales, using surveillance and undercover drug buys to gather evidence.

Upper Darby police superintendent Michael Chitwood says they do these drug sweeps about three or four times a year.

“The main goal on these drug sweeps is to give people back a quality of life that these communities deserve, and rid the corners of our community of these drug dealers,” he said today.

Police seized three vehicles and several thousand dollars in cash, plus drugs and cell phones.

The charges against the suspects range from drug dealing to possession of drugs and drug paraphernalia.
