Three people were injured Saturday in a knife attack at Paris's Gare de Lyon railway station, a major travel hub, police said, adding that a suspect had been arrested and placed in detention. 

The man, a Malian national, went on a stabbing spree at around 7:35 am (0635 GMT) at the station, which operates domestic trains as well as those heading to Switzerland and Italy.

One person suffered serious injuries to the abdomen while two others were lightly wounded, police said.

A terrorist attack has been ruled out at this stage and an enquiry launched.

Sources said the man appeared to be homeless and suffering from psychological problems.

Paris prosecutors said the suspect could have used a knife and a hammer that were under analysis.
