PHILADELPHIA -- We have all been bothered by those pop-up advertisements while trying to search the Internet. Recently those annoying ads also plagued the Philadelphia Police Department.

There have been computers on board police patrol cars for a number of years. They are called MDTs, or mobile data terminals. They are now as much of a part of police equipment as a gun or a radio.

"The information gets updated in the MDT as you're in route to the scene," said Sgt. Thomas Macartney.

Information is what officers normally see and expect to see on their computer terminal screen. But a week ago Saturday, some of the cops using the 300 newest MDTs had quite a surprise.

They got a pop-up advertisement for a pill similar to Viagra on their screens.
