It still isn't clear why the attack happened. Police said there is no indication that it is tied to terrorism.

Images circulating online show two people lying flat on the ground outside a branch of the UBS bank.

Eyewitnesses suggest a number of shots were fired during the incident. It is also not clear whether the police have apprehended the shooter, but there is a heavy police presence on the ground.

Authorities told local media they were responding to an incident in downtown Zurich, near the Swiss financial hub's main train station.

Police confirmed in a tweet that the incident had happened on Lagerstrasse, a road running right through the centre of Zurich.
