Police had sought Abdeslam since he called two acquaintances in Belgium in a panic, hours after the attacks, to have them collect him and bring him home.

Suspected to be as far away as Syria, it seems he was in Brussels all or most of the time.

Failure to complete his mission could have limited his access to any support from Syria-based Islamic State; the chief Belgian investigator on the case said he had instead relied on a network of friends, family and neighbours with whom he had a history of drug trafficking and petty crime.

Security agencies' difficulties in penetrating some Muslim communities, particularly in pursuit of Belgium's unusually high number of citizens fighting in Syria, have been a key factor in the inquiry.

Paris relief

As Parisians, and families of the victims, voiced relief at the arrest, French Interior Minister Bernard Cazeneuve said after an emergency cabinet meeting that a trial could answer questions for those who suffered in the attacks.

"Abdeslam will have to answer to French justice for his acts," he said. "It is an important blow to the terrorist organisation Daesh (Islamic State) in Europe."

A trickle of people came to a makeshift memorial in central Paris, near the scene of much of the bloodshed, to pay their respects.

"It's really a relief," said Emilien Bouthillier, who works in the neighbourhood. "I can't wait for Belgium to transfer and return him to France so he can be tried the way he should be."

Friday's armed swoop came after Abdeslam's fingerprints were found at an apartment following a bloody raid on Tuesday in which an Algerian was shot dead and police officers wounded.

Later, local media said, a tip-off and a tapped telephone led police to a mobile phone number used by Abdeslam and, by triangulating the device's location, established where he was.

At his nearby newspaper store, a vendor named Dominique said Abdeslam had been well known and liked in the community: "He was a very nice lad before," he said. "How can things go this far?"
