Salah Abdeslam, a Belgian-born French national wanted in connection with last week's deadly Paris attacks that claimed 129 lives, was on Monday reportedly arrested in Brussels.
The 26-year-old was captured alive in an operation by Belgian special forces in Molenbeek, an impoverished suburb of Brussels with a history of links to terror plots, Sky News reported citing Belgian broadcaster RTL.
Reports suggested that he was seen at a window of a building with his arms up in the air, before police used tear gas to neutralise him.
However, Belgian public broadcaster RTBF said he was not arrested.
Raids have been taking place in Molenbeek since the early hours of Monday. At least two roads were cordoned off by the police in an active standoff, CNN reported.
Seven people were arrested in relation to the Paris attacks in raids in Molenbeek.
