METHUEN (CBS) – Two people have been arrested after a man who was selling car doors outside a McDonald’s in Methuen was shot twice late Monday night.

Police said the man posted the sale information for two car doors on the “Offer Up” app and met the buyers at the restaurant parking lot on Haverhill Street just before 11 p.m.

Investigators said surveillance video showed 10 people getting out of three vehicles and the doors were taken from the man. One person started shooting – firing 11 rounds, hitting the man twice.

“He ended up assaulting him physically and you see he draws a gun,” said Methuen Police Chief Joseph Solomon. “He has the gun down he ends up shooting him a couple of times.”

Police say 42-year-old Henry Infante was the gunman. He was arrested Tuesday night on several charges including assault to murder. Yolanda Hernandez, 42 of Lawrence was arrested and charged with assault and battery and accessory after the fact.

The car doors matched a pair recently stolen from Hernandez.

The victim stumbled into the restaurant with gunshot wounds and the group took off.

“So far I think we’ve accounted for 11 rounds so the man is very lucky that he was only shot twice and we’re lucky that no one else was shot,” Methuen Police Chief Joseph Solomon told reporters Tuesday.

“I would like to say though there was a Good Samaritan inside the store. When the man came in injured, it’s obvious the man inside knew what he was doing. He provided first aid, applied pressure. Put clothing on the wounds. So we’d like to thank that individual for his heroic actions.”

The wounded man, a 21-year-old from Lawrence, was rushed to Lawrence General Hospital, but is expected to be okay, according to police.
