Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
