STAMFORD - Stamford police have arrested a group of teens who they say pistol-whipped and robbed a pizza delivery man.

Three of them are students at Stamford Academy.

Police say the driver was trying to deliver a pizza to a fake address when he was attacked on West Broad Street back in February.

They say four people beat him up, stole his money and took his car.

Investigators say they tracked down a 17-year-old through phone records and arrested him this week at school.

They say two others were arrested last week when they were linked to stolen credit cards.
