A pilot, who was filmed apparently pushing a policewoman in Kenya, is due to appear in court on Wednesday.
Alistair Llewelyn, who police say is a British citizen, had been hired to fly Kenya's Deputy President William Ruto to a political rally on Sunday when the incident occurred.
In the video, which went viral, Mr Llewelyn is seen shouting at the policewoman to control a crowd.
Police say he handed himself in after an investigation was launched.
Police spokesperson George Kinoti said that he is facing assault charges.
BBC Africa's Emmanuel Igunza says the video has been widely shared on social media, with many Kenyans using a hashtag calling for the deportation of the pilot.
In the video, Mr Llewelyn is seen calling on the policewoman to do her job and control a crowd milling around the helicopter.
He then appears to grab the policewoman's stick and moments later, seems to shove her towards the crowd.
Kenya's deputy president has described the incident, which took place in Ndunyu Njeru, about 60 miles (100km) north of the Kenyan capital Nairobi, as "unacceptable and regrettable".
The company which had hired Mr Llewelyn says it has ended his contract.
