A 19-year-old man is facing a charge of elevated aggravated assault after allegedly stabbing an acquaintance in Biddeford on Sunday.

Anthony S. Lapointe, described by police as a transient, was arrested after a 22-year-old Biddeford man went into the Papa John’s Pizzeria on South Street with multiple stab wounds around 1 a.m. Sunday.

The victim told police who responded to the pizza shop that he was stabbed by Lapointe, said Deputy Chief JoAnne Fisk. Officers followed a blood trail and determined the likely crime scene was 84 South St. The victim – whose name is not being released because he has not yet been questioned by police – told investigators that he knew Lapointe and the two had met up earlier at Dunkin Donuts on Spruce Street.

After police reviewed security footage from Dunkin Donuts, they identified two female witnesses. Those witnesses later told police that the victim was acting irrationally and one said she had seen Lapointe hit the victim, but never saw a knife, Fisk said.

After the fight, the women left the doughnut shop with Lapointe and, as they walked down the street, noticed he was bleeding from his right hand. Lapointe told the women that he stabbed the victim with a knife, according to police.

Police later recovered the knife, which had blood and fibers on it matching the victim’s clothing.

The victim was taken to Maine Medical Center in Portland, where he is in stable condition.

Fisk said police have yet to determine a motive, but suspect the fight was over a woman.

Lapointe is being held at York County Jail on $25,000 cash bail.
