A man has been arrested on suspicion of assault after a number of people were sprayed with what is believed to be pepper spray at a Heathrow Airport car park, police said. A group of people who knew each other were involved in an argument which escalated and resulted in people being injured, police said, with other suspects being searched for.

One man was arrested after a substance that appeared to be pepper spray was used during a fight in one of the airport’s parking garages, the police said.

Airport police said in a statement they were called just after 8 a.m.

Democratic Rep. Adelita Grijalva says she was pepper-sprayed and shoved by federal agents during an Immigration and Customs Enforcement operation in Tucson, Arizona — the latest flashpoint in the Trump administration’s escalating immigration crackdown.

LONDON: United Kingdom armed police arrested a man on Sunday (Dec 7) for suspected assault after 21 people needed medical treatment following an incident involving "a form of pepper spray" at a Heathrow Airport car park.

U.S. Rep. Adelita Grijalva said she was pepper-sprayed Dec. 5 during protests responding to an immigration enforcement raid in Tucson. Protesters had assembled near Taco Giro, a Mexican restaurant that U.S. Immigration and Customs Enforcement had raided earlier that day.
