German police have stormed a pharmacy in Cologne’s central railway station, freeing a woman who had been held hostage by a man for two hours.

A male suspect sustained life-threatening injuries in the incident. It was not immediately clear how he was injured. Police said on Twitter that emergency personnel were carrying out CPR.

The woman sustained minor injuries and was treated at the scene.

At around the time of the incident, a teenage girl was taken from the station to hospital, said Christoph Schulte, a police spokesman. He did not confirm local media reports that the suspect attacked the girl before taking the woman hostage.

No information as to the suspect’s identity or motive was provided by police.

Before officers stormed the pharmacy, the station – one of the busiest in Germany – was evacuated and all trains were stopped, leading to delays and cancelations across western Germany.
