A top Italian paparazzo who took pictures of Brangelina, Beyonce and dozens of other celebrities has been found shot dead.

Daniele Lo Presti, 42, was discovered on a riverside with a single bullet wound to the head, the classic sign of an ordered hit.

Murder squad detectives launched an investigation following the discovery of his body and have not ruled out the possibility he was killed after "crossing" someone in his business.

Mr Lo Presti was found in the Testaccio district in the southwest of Rome on a cycling track where he regularly went jogging.
