PITTSBURGH -- A man sitting in a car outside of a South Side Giant Eagle tackled and held a suspected bank robber until police could get there, officials said.

Investigators said a man tried to rob the Citizens Bank inside of the grocery store on Wharton Street Wednesday morning.

Witnesses say a jitney driver who was sitting outside of the store saw a man running out of the building. They said the driver jumped out of his car and tackled the would-be robber.

The driver said he held the man until police got there.
