Southampton City Council has said it has secured the entrance to the roof of a tower block after two people were seen BASE jumping from it.

On Thursday evening two people were seen leaping from the 240ft towers before opening a parachute.

Footage captured at the time went viral on social media.

At the time the city council said it had launched an investigation with a councillor describing the actions as "utterly idiotic".

The city council has now said that its teams have secured the entrance to the roof of the tower block on Windermere Avenue.

A spokesperson said: “Our team has secured the entrance to the roof area once again, so there is no risk of anyone being able to access this. As our investigation is ongoing, we are not in a position to provide any further details at this time.”

Millbrook councillor Jeremy Moulton had previously slammed the actions, telling the Echo: "They are lucky not to have killed themselves or to have hurt someone else.

“The council is urgently investigating how the person got access to the roof and I would ask that the council investigates all of its tower blocks to ensure people can't get access to the roofs.”
