Undercover UK journalists deported from Bahrain
A team from Channel Four News, led by foreign correspondent Jonathan Miller, has been deported from Bahrain, the Foreign Office says.
The journalists had been denied media accreditation to report on protests surrounding the Formula One Grand Prix, but entered the country as tourists.
Mr Miller told BBC Radio 5 Live they were pursued by riot police officers and a helicopter prior to arrest.
He was detained along with cameraman Joe Sheffer and producer Dave Fuller.
He said: "We were in a particular village where we were filming a small demonstration of mostly kids when we realised that we were being monitored by a police helicopter.
"We looked in our rear view mirror and suddenly realised that a large number of riot police were literally charging us from behind. So we set off at high speed.
"The helicopter stayed across us for about two or three miles I would say. There was a police car behind us and eventually we ran into a checkpoint. We were cut off by the police, held for about an hour inside our vehicle by scores of riot police, many of them wearing balaclavas, being quite rough, quite abusive. My driver was injured."
There are concerns about the welfare of the driver, and also Anglo-Bahraini human rights activist Dr Ala'a Shehabi, who was travelling with them.
The driver, who has not been named, was arrested and assaulted and Mr Miller said Dr Shehabi had her arm slammed in a car door by riot police.
Dr Shehabi later tweeted that both she and the driver had been released by police.
She said: "Back home after 7 hours in police custody & a dramatic arrest-with a helicopter on the tail of our car."
The grand prix went ahead, despite protests and calls for a boycott, and was won by Germany's Sebastian Vettel.
