Two more people are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. A total of five individuals went to hospital for treatment and were later released.
Officers arrested a man in his thirties on suspicion of robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
