A blood-covered Texas man who knocked on doors in a neighborhood begging for help was then shot by a homeowner after forcing his way into a property, according to police.

The Houston Police Department says the man is in critical condition at a hospital in the city following the confrontation, ABC13 Houston reported.

The incident began shortly after midnight on Monday when witnesses reported seeing two men running near Campden Hill. One man was reportedly wearing a mask, while the other was bleeding from the head.

According to investigators, the bloodied man began a frantic circuit of the neighborhood, knocking on the doors of several homes. Video footage obtained by ABC13 captured the man shouting for help and banging on a door before he eventually reached a property in the 4800 block.

Authorities say the man kicked in the front door and forced his way inside the house, where he was subsequently shot by the homeowner.

According to KHOU 11, a CBS affiliate in Houston, Lt. J.P. Horelica stated that investigators believe both suspects are in their early 20s.

The masked man was described as wearing a black hoodie and a jumpsuit. He fled the scene on foot in an unknown direction and remains unidentified.

Police have not yet determined the cause of the man’s initial injuries or whether he had been assaulted before the break-in.

Residents of the quiet suburb expressed shock at the violence.

Gerald Conkrite, a neighbor, told reporters that such events are a rarity for the area.

“We don’t have that over here,” Conkrite told ABC13. “It don’t work like that over here no more.”

KHOU 11 reported that investigators are also asking residents to review home-surveillance footage from the neighborhood to track the suspects’ movements before the shooting.
