An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries 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 on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be an irritant spray.
The attack - an event that police said was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
