Fourteen people were treated by medics at a Selfridges this afternoon after a man released an ‘unknown substance’ on the shop floor.
A man in his 20s was detained by security and arrested on suspicion of affray after he sprayed another man with the irritant in the Oxford Street department store.
Metropolitan Police said the substance, which has not been identified, caused similar effects to the riot control agent CS gas.
Several customers and employees who were inside the store were treated at the scene, but medics are said to be ‘confident it is a non-harmful irritant’.
A Selfridges spokesperson said ‘a few team members and customers were checked over by the ambulance service for an irritated nose and throat’ following the incident.
All but one customer, who continues to be monitored, were ‘given the all clear’, a statement added.
