St Joseph police arrested a man Monday morning who they believe was breaking into cars.

Based on police radio traffic, the man was caught in the act by a passerby who called police. An officer deployed a taser during the arrest of the suspect in or near the 1500 block of Frederick.

Police Sergeant Brett Kelly tells us at least three cars were affected, although it’s not clear if property was stolen from all of them. In at least one case, nothing was taken.

It appears from radio traffic that the suspect may have taken a saw and a ratchet set, a set of jumper cables, and a lot of change. That investigation continues. No charges have been filed.
