An 18-year-old Lawrence man was arrested early Saturday for robbery, domestic battery and theft under $1,000 after a physical altercation with a 19-year-old Lawrence woman.

Sgt. Ted Bordman of the Lawrence Police Department said the altercation occurred on the 1300 block of Massachusetts Street about 1:50 a.m. Bordman said the suspect confronted a male accompanying the victim, who had a previous relationship with the suspect. The confrontation became physical, and the suspect stole the victim’s keys, cellphone and purse. He then ran south and was soon arrested on the 1400 block of Vermont Street.

No one was injured, and police returned the items to the victim.
