POLICE attended a scene in Maida Vale in the early hours of this morning to reports of someone acting suspiciously.
Reports from the scene claim someone had poured "petrol" at the entrace of a residential building.
Police confirmed a "spillage" to Express.co.uk, adding there had been one arrest.
There were also claims of a 'gas leak' and an injury in the area, though police confirmed neither of these claims were true.
The situation has now been resolved, it is understood. The road has since reopened.
A social media user at the scene snapped photos of emergency vehicles attending Maida Vale's Tolgase House earlier tonight, including at least two fire engines.
