An additional two individuals are now in custody in connection with 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 man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
