Two more people are now in custody related to a theft at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. Five people were taken to the hospital for treatment and were later released.
Officers arrested a 31-year-old man for suspected theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
