Discarded parking ticket in a car near the Bataclan leads detectives to arrest a man in Brussels, Belgium

When detectives discovered a grey VW Polo car with foreign licence plates near the Bataclan concert hall after the bloody attacks in Paris, they suspected it would offer clues to the assailants who had wreaked such terror on the city hours earlier. This is because eyewitnesses had said that the terrorists were black-clad men appearing from cars bearing Belgian plates before they started shooting and killing 129 people.
A parking ticket found in the small rented vehicle was to tell them much more than they could have hoped – or, indeed, have feared. It had been issued in the Brussels district of Molenbeek.
Immediately the French security services alerted the Belgian Police who in turn raided a Brussels neighbourhood in connection with the atrocity in Paris.

Belgian TV news reported an arrest has been made in the suburb of Molenbeek and a video posted on Twitter showed a man being handcuffed by what appear to be plain clothes officers and uniformed cops with guns as he lies face down on a wall.

The name of the person who rented the VW used by the attackers was linked to the person arrested in Brussels.
An bomb disposal team also arrived at the scene to determine whether there were explosives in the apartment.
