GLENDORA — A parolee was behind bars Saturday on suspicion of head-butting a woman and seriously injuring her, police said.
Ryan Laing, 38, of Azusa was arrested at his home and booked on suspicion of felony battery about an hour after the alleged attack, which occurred just before 10 a.m. in the 900 block of Walnut Avenue in Glendora, Glendora police Lt. Rob Lamborghini said.
There was an argument between Laing, his girlfriend and the alleged victim, who was an acquaintance of the girlfriend, prior to the attack, the lieutenant said.
Laing head-butted the alleged victim, a 34-year-old Glendora woman, causing a large gash to her head, said Lamborghini.
The woman was hospitalized and released after receiving 17 stitches, he added.
Police tracked Laing to his home in the 1000 block of E. Gaillard Street in Azusa shortly after the incident, Lamborghini said, and he surrendered when officers surrounded the home and ordered him out.
He was being held without bail, he said, and was expected to be arraigned Monday in West Covina Superior Court.
