THE BRONX - A Bronx man is defending himself after reports surfaced that he abandoned a patient in his ambulette van amid Wednesday's deadly building explosion in East Harlem.

Miguel Bicaino says that when he first heard the blast, he thought it was a bomb going off on a passing train. His van was covered in debris and its windows were blown out.

After hearing it, he says he ran to get help, but says the police officer he flagged down would not let him return to his van. 

Bicaino also says the patient's home attendant was in the back at the time of the explosion, and claims that she fled when he opened the back door.

Samuel Carrasquillo, a passing deliveryman, says he helped the stranded patient as soon as he noticed her.
