Three people have been arrested in France after a Burkina Faso-born man was beaten to death by a group of teenagers in Pau, in the south-west of the country.

The 32-year-old Frenchman was murdered outside a park early on Friday evening.

The victim, who had moved from the French capital, Paris, to Pau recently, had been known to the police in Paris, but "had not been talked about since early 2018", Pau prosecutor Cécile Gensac said on Monday.

He had previously been convicted of aggravated robbery and drug trafficking between 2010 and 2015, according to regional daily Sud Ouest.

But "no link has been established between his past and the events that occurred on Friday night in Pau", the prosecutor added.

An investigation is under way, and an autopsy is due to be performed on the body.
