Authorities say at least four people have been shot at an Atlanta public transit station.

Metropolitan Atlanta Rapid Transit Authority spokesman Erik Burton says in a statement that the shooting happened about 4:30 p.m. Thursday at the West Lake station, which has been temporarily closed.

There was no immediate word of the victims' conditions.

Burton says police have detained a suspect but further details were not immediately released.

He says MARTA has set up a bus between stations to accommodate customers during the closure.
