The pap could face a year in jail & a £36k fine if found guilty...
It is thought that the snapper's name has been handed over to the authorities who are investigating the incident, after a criminal inquiry was launched last month when French Closer magazine first published the intimate snaps.
A source has now told The Daily Mail: "A name has been offered. The photographer is expected to be held for question[ing]... imminently."
French public prosecutor Marie-Christine Daubigney stated: "This new information regarding the photographer will be passed on to investigating magistrates."
The Metro has also reported that the pap is thought to be one of a "notorious band" of press who followed William's mother Princess Diana in the week leading to her death in 1997.
A Royal insider added to The Mirror: "William and Kate are determined to bring the person who took those photos to justice and they're pushing hard for a custodial sentence. They want to make an example of this person."
The paparazzo - who is rumoured to be an Englishman living in the South of France - could face up to a year in jail and a fine of £36,000 for breach of privacy if found guilty.
