DETROIT -

Detroit police say a suspected gunman surrendered Tuesday morning after roughly a three-hour standoff in a home on the city's west side.

Detroit Police Commander Elvin Barren said the situation started around 4 a.m. with an argument between the suspect and his girlfriend in the 2700 block of Collingwood Street.

Barren said the girlfriend found another female in the home and a dispute broke out. The girlfriend said the suspect scratched her on the neck and then fired a shotgun into the air. No one was hurt, but the boyfriend then refused to come out of the home for police.

Barren said both women were able to get out of the home, but negotiators were called in to work with the suspect -- who eventually surrendered around 7 a.m.

Barren also said the suspect is a parolee who has a history of narcotics-related crimes.

"He could possibly go back to prison for a long time," Barren said.
