ALLENTOWN, Pa. | After the sound of arguing caught the attention of Allentown police Wednesday, officers happened upon a stabbing victim and quickly arrested his accused attacker.

Allentown police arrested Theodore McCalman Wednesday afternoon after he allegedly stabbed a man inside North Church Street home. District Judge Jacob Hammond arraigned the 43-year-old a few hours later on a single felony count of aggravated assault.

Allentown police were responding to an unrelated call shortly after 3:30 p.m., when the sound of arguing drew an officer’s attention to a home in the 200 block of North Church Street. The officer spotted a man later identified as McCalman running from the house, according to court records.

As the officer approached the house, he encountered the victim standing in the front door with a “pool of blood” on his shirt, pointing to McCalman as the man who just stabbed him, according to police. Officers gave chase, ordering McCalman to stop. Police said he did stop running and was taken into custody.

The victim, meanwhile, suffered two stab wounds to his chest and back. He was taken to Lehigh Valley Hospital Cedar Crest for immediate surgery. Police said in a news release that the victim is in stable condition.

Police said McCalman and the victim “were known to one another” but did not offer a motive for the attack.

McCalman failed to post $250,000 bail and was sent to Lehigh County Jail to await a preliminary hearing scheduled for Oct. 23.
