Regional broadcaster Bayrischer Rundfunk (BR) is reporting that a knife attack at a train station outside of Munich in the early hours of Monday morning has left four people injured, one of them critically.

BR reports that a young German man with no previous police record attacked passengers at an S-Bahn overground train station in Grafing, a town east of Munich. The attack occurred around 5 a.m. local time.

Police are investigating witness statements that the man yelled "Allahu Akbar" – an Islamic saying meaning 'Allah is great' – before carrying out the attack.

The suspect was overpowered by police and is now in custody.
