A new photo shows Paris terror suspect Salah Abdeslam staring glumly at the camera inside a Belgian high-security lockup — where he’s described as a model prisoner.

“He’s a very good boy,” a prison source told the Het Nieuwsblad newspaper. “His behavior is an example to many of the other inmates. There hasn’t been a negative word about his actions — and his appetite is excellent.”

A guard in the Bruges lockup checks on Abdeslam, 26, eight times an hour for fear he might harm himself, reported the Flemish paper, which published the image Tuesday.

The French national, who was arrested March 18 in the Brussels district of Molenbeek, is expected to be transferred to France to stand trial for allegedly planning and helping to carry out the attacks in Paris that killed 130 people on Nov. 13.

He has told investigators that he had planned to carry out a suicide bombing at the Stade de France stadium, but backed out and fled to Belgium, prosecutors have said..

His arrest is believed to have sparked the attacks in Brussels that killed 35 people on March 22.

Mohammed Abrini, who helped drive Abdeslam to Paris, was arrested last week in Belgium.

He has admitted to being “the man in the hat” seen walking with suicide bombers Najim Laachraou and Ibrahim El Bakraoui at the Brussels airport.

Abrini, 31, has been charged with terrorist murders, prosecutors said.

Abdeslam’s brother, Brahim, blew himself up in a coffee shop during the attacks in Paris.
