Members of the Guardian Angels, a volunteer crime patrol group, began riding some CTA buses Tuesday to protect passengers after a rash of purse snatchings.

The group is focusing on the 55th Street buses running between Halsted and King Drive.

Chicago police issued an alert Monday about the thefts. All of the incidents have happened this month.

The Guardian Angels say their members will make a citizen's arrest if they see anyone committing a crime.
