The Swiss police say the woman died from injury she sustained after the attacker knifed her and others with a knife and a burning liquid aboard a train.

The late train commuter reportedly died Sunday morning, St. Gallen canton (state) police said.

According to a BBC report, a total of seven individuals were wounded in the attack with four others including the suspect currently in critical condition.

Police spokesman Hans-Peter Kruesi revealed that authorities are yet to  interrogate the 27-year-old suspect, who is a Swiss man from a neighboring canton.

Kruesi said so far police have found no indications the man had ties to extremist groups.
