Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
