A Philadelphia police officer shot a 35-year-old man in the chest on Friday after he allegedly reached for behind his back where an officer had previously spotted a handgun. 

Robert Judy was listed in critical but stable condition after he was taken to Hahnemann University Hospital.

According to police, officers were called to the area of 8th and Green Streets for a call of a man with a gun. While on their way, callers directed officers to 8th and Fairmount. 

Judy was facing away from Officer Michael Haas,who noticed a gun in his waistband. Police say that when Judy was ordered to show his hands, he turned to face officers, began walking backwards and reached toward the gun in his waistband. 

Judy was shot once in the chest after Haas fired. 

Haas, a 7-year veteran, was placed on administrative leave, as is policy for all officer-involved shootings. 

Friday's shooting was the first since police announced in July that they would name officers who discharged their weapons. Two days after announcing the policy, the department revealed the names of two officers involved in a shooting in May. 

Philadelphia's police union opposes the policy, saying it endangers officers.
