Delaware State Police say a man is in critical condition after a trooper shocked him with a Taser after the man showed a handgun.

Troopers said in a news release Thursday that police went to the Milford home to arrest a man late Sunday. Authorities say a man at the house, who was not the man police came to arrest, refused to let them enter.

Police say when the troopers started to leave, the man, 35-year-old Lionel Waters, opened the front door and said he had a weapon.

Authorities say troopers saw a firearm, one shocked Waters with his Taser and Waters struggled with them.

Police say Waters lost consciousness and was taken to a hospital, where he was in critical but stable condition.
