A gunman opened fire inside a German nightclub Sunday morning, killing a bouncer and wounding four before he was fatally shot by police,

authorities said.

The gun battle broke out in the southwest German town of Konstanz, with three people wounded inside Club Grey at about 4:30 a.m. and a policeman shot with non-life-threatening wounds, police said.

The gunman was identified as a 34-year-old Iraqi citizen who lived in Konstanz. He’s the son-in-law of the club’s owner, officials told the BBC.

The killer had argued with staff, was thrown out and came back armed with a M16 machine gun, said Andreas Stenge, a spokesman for the Baden-Württemberg criminal investigation office.

Local police knew the gunman from previous encounters and said the attack had no terror ties.

“We are still investigating but the circumstances surrounding the events at the disco in the evening before the shooting are a bit clearer and this led us to rule out a terrorism background,” police spokesman Fritz Bezikofer told N-TV.

Unless the gunman became a radical in hours between being thrown out and returning armed, this wasn’t an act of terrorism, cops said.

“According to our investigations this is not terror-related, unless the gunman radicalized himself within the last three days,” Bezikofer told CNN. “At this moment we believe that he may have had alternative motives.”
