A doctor is being treated in intensive care after being stabbed at a medical practice in The Hague.

The man, who was working as a stand-in doctor, was attacked inside the Zuiderpark Huisartsen practice in Apeldoornsestraat at around 10.30am on Tuesday.

A 38-year-old man was arrested after he was restrained by people who witnessed the attack and is currently in police custody. He is due to appear in court on Friday.

Police have not given any indication of the identity of the attacker or what his motive might have been.

A man working in a neighbouring shop told the Telegraaf: ‘I heard from a patient who was in the waiting room that the perpetrator, a neatly dressed man, walked out very calmly.’

A spokesman for Hadoks, a group of medical practices in the Haaglanden region including Zuiderpark Huisartsen, said: ‘We are greatly shocked by this violent incident.

‘It has had a huge impact, first and foremost on the victim and his family, but also on the staff at the practice.’

A spokesman for the family doctors’ association LHV said: ‘It’s terrible that something like this has happened. It has had a big impact on the practice and its staff. Our thoughts are with them.’
