Two more people are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 on 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 during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be an irritant spray.
The assault - which police said was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
