Paris attacks suspect Salah Abdeslam
was allowed to leave France because Belgium did not tell police in time
that he was involved in jihadist circles, a senior French MP has said.
| Salah Abdeslam is now being held in a four-cell complex at Fleury-Merogis jail south of Paris |
He was in a car with two other men and held for 30 minutes, because his name was on a Schengen Information System (SIS II) file, which allows countries in the passport-free area to issue alerts on criminal suspects.
However, the file only held information about Salah Abdeslam's criminal past and not his links to militant Islam. "While Salah Abdeslam was known by Belgian authorities to belong to the jihad movement, for what reason did this information not appear in the file?" Mr Pietrasanta told AFP news agency ahead of his full report on the case on Tuesday.
That information was eventually passed on, more than an hour after he was allowed to cross the border.

Belgian officials have already indicated that they were close to arresting Salah Abdeslam at a house in the Brussels area of Molenbeek in the early hours of 16 November, but had to wait until after 05:00 to comply with law banning overnight police searches.
It was not for another four months that he was caught, four days before bomb attacks on Brussels airport and the Brussels metro in which 32 people died.
