An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Police detained a man in his thirties on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
