Two men have been charged with robbery and administering a noxious substance after an incident at Heathrow airport on Sunday.
Tyrone Richards, 31, and Anton Clarke-Butcher, 24, have each been charged with two counts of robbery and two counts of administering a noxious substance, HM Courts and Tribunal Service staff said.
They are due to appear at Hillingdon Magistrates’ Court charged with robbery on Tuesday.
The Metropolitan Police said it has made a number of arrests in connection with the incident.
Three more people were arrested on Monday, including a 23-year-old woman on suspicion of conspiracy to commit robbery, who was later released on bail pending further enquiries.
A 57-year-old woman was also arrested on suspicion of conspiracy to commit robbery and was later released under investigation, and a 31-year-old man was arrested on suspicion of affray and remains in custody.
Police were called to a multi-storey car park opposite Terminal 3 at 8.11am on Sunday after receiving reports that a number of people had been injured by a noxious substance.
London Ambulance Service treated 21 people, and five people were taken to the hospital, but have since been discharged. Among those injured was a three-year-old girl.
Prior to the assault, two women were robbed of their suitcases after getting out of the car park lift. The men who robbed them sprayed a substance believed to be pepper spray in the direction of the women, which then affected others nearby.
The assault sparked chaos for many travellers as several trains and buses to the airport were delayed, with several people reportedly stuck at the airport’s bus stops for hours.
At least 17 trains serving Heathrow Terminals 2 and 3 were cancelled, or ran through without stopping.
