BIDDEFORD — A 19- year-old transient has been charged with aggravated elevated assault after admitting to stabbing a South Street resident early Sunday morning.

Around 1 a.m. Sunday, the 22-year-old victim walked into Papa John’s pizzeria at 22 Elm St. with multiple stab wounds and named Anthony Lapointe as the attacker, according to a press release from Biddeford Police. Police are not releasing the victim’s name.

Police followed a blood trail and found the likely crime scene on South Street.

The victim told police he met with Lapointe earlier at Dunkin’ Donuts on Spruce Street. Police went to the Dunkin’ Donuts and reviewed surveillance footage of Lapointe, the victim and two women.

The women were identified and interviewed by police. They said the victim had been acting very irrationally. One said she witnessed Lapointe striking the victim; however, she thought the accused used his fists and did not see a knife.

After the alleged stabbing, the two women and Lapointe walked down Elm Street toward Saco. One of the women noticed blood coming from Lapointe’s right hand and asked him about it, and Lapointe admitted to the two women that he had stabbed the victim, according to witness accounts.

The women assisted detectives in getting Lapointe to turn himself in to the Biddeford Police Department, and Lapointe admitted to stabbing the victim with a knife, police said.

Lapointe was taken into custody and charged with elevated aggravated assault. Bail was set at $25,000. He was unable to make bail, and was taken to York County Jail.

The knife used in the alleged stabbing was recovered with blood and fibers matching the victim’s clothing, police said.

The victim was transported to Maine Medical Center, and was listed in stable condition Monday. The victim’s condition was unavailable this morning.

Police have not determined a motive but believe the alleged stabbing was over a woman.
