Security is being stepped up at Portsmouth’s crucial League One play-off match with Sunderland tonight (Thursday) after an online threat was made to ‘shoot and bomb’ fans.

Threats, posted by a user on Twitter, referenced the Manchester Arena bombing which killed 23 people in May 2017, according to the Mirror.

Fans from the Isle of Wight are expected to make the journey across the Solent to the game this evening.

The user said:

“I wounder (sic) how many Portsmouth fans I can shoot everyone remember the Manchester arena bombing just imagine fratton park going bang well let’s find out tomorrow.”

It was followed by:

“Bomb bomb fratton park went bang the Portsmouth fans all died Haha going to be fun tomorrow headline news.”

The threats have been reported to the police, who are investigating the matter ahead of the sold-out Sky Bet League One play-off semi-final second leg at Fratton Park. Sunderland lead 1-0 on aggregate.

The Twitter account has since been suspended.

A Portsmouth FC spokesperson said:

“The club would like to reassure fans that there will be enhanced security checks in place for Thursday’s play-off match against Sunderland at Fratton Park (7.45pm kick-off).

“Due to these checks, all supporters with tickets are advised to arrive in plenty of time to make sure they are inside the stadium for the start of the game.”
