SHEBOYGAN, Wis. (WHBL) -  A Sheboygan man is being sought by police after a domestic dispute in a home in the 1600 block of Heller Avenue Monday night.  Captain Steve Cobb said officers were called to the home about 6:30pm after the 40 year old suspect had threatened to shoot himself and the woman he lives with.  Cobb said she was able to flee to a neighbor’s home and call police.  Officers surrounded the home but, by that time, the suspect had left.  Cobb said police found a BB-gun, which was apparently involved in the incident, but there was no evidence that the man was ever armed with a real firearm.  He said there is no immediate danger to people in the neighborhood and efforts to locate the suspect are on-going.
