Omaha police say they've arrested a man who broke into his ex-wife's home while armed with a hammer. 

Tim Conley was arrested Monday and booked for domestic assault and obstructing justice. 

Police say Conley  broke open his ex-wife's front door. They say the woman and her roommate locked themselves in the basement and called police.

Police say Conley wouldn't come out of the house. They say a police dog bit him and an officer shot him with a Taser. 

He is being held at the Douglas County jail on $100,000 bond.
