Former English Superbike racer Sean Emmett has been arrested on suspicion of murder after returning to the UK.
Emmett, 43, had his passport given back to him by officials in the United Arab Emirates months after a probe into wife Abbie's death was concluded. He flew to the UK from Dubai earlier today and was held by police upon his arrival at Heathrow Airport.
Mrs Emmett, 27, died on the couple's honeymoon in February after falling several floors from a high-rise hotel in Dubai.

A Surrey Police spokesman said: "A 43-year-old man has today been arrested by Surrey Police officers at Heathrow Airport in connection with the death of Surrey resident Abigail Emmett, née Elson, in Dubai in February 2013.
"The man remains in custody while inquiries continue and it would be inappropriate to comment further at this stage."

Emmett had been stranded in the Gulf state since his passport was handed to officials during the investigation. Before his arrest, he had posted a picture of his newly returned passport on Twitter, describing it as the "best early Xmas pressie ever".
He wrote on the social networking site today: "Thanks to everyone for all your messages, my phone's melting!! Flight booked and I'll be landing in Blighty 7.10 tmrw. #bringonthecold."
Last month Mr Emmett sent a message of thanks to supporters on Twitter, writing: "Just want to thank each and every one of you that has helped me with support, financial or otherwise. I don't even have contacts for some!"
