British police have arrested a 19-year-old man in connection with the murder of two French students in London in June.

Seven people have now been arrested as part of the investigation into the deaths of Laurent Bonomo and Gabriel Ferez, both 23, on 29 June.

Two men, 33-year-old Nigel Farmer and 23-year-old Daniel Sonnex, have already been charged with the murders of the two French students.

The students were on an exchange programme at London's prestigious Imperial College from their university in Clermont Ferrand in central France.

The pair, who were due to return home at the end of July, were found bound, burned, and repeatedly stabbed in a southeast London apartment.
