An off-duty Baltimore police officer on Friday morning shot a 26-year-old Baltimore man who was attempting to burglarize the officer's Dundalk home, according to city and county police.

Antonio Lionell Fenwick of the 1900 block of E. Belvedere Avenue was found shot in the officer's living room at about 6 a.m. in the 1800 block of Willow Spring Road, according to a preliminary investigation.

A county police spokesman said it was unclear if the suspect was armed. Lt. Robert McCullough, the spokesman, said the man was going through the officer's items and was near unlocked weapons when he was spotted by the officer, who came from his upstairs bedroom after hearing the commotion. The suspect was shot once in the upper body after a brief confrontation, McCullough said.

Fenwick was transported to the Johns Hopkins Bayview Medical Center where he is in critical condition, McCullough said.

According to electronic court records, Fenwick had previously faced charges including theft, assault and armed robbery in 2001 but was not convicted.

The officer, who was not hurt during the altercation, is an 18-year veteran of the city Police Department, according to McCullough. He has been placed on administrative leave pending the outcome of the investigation, which is being led by the county department.
