BEYONCE BEEFS UP SECURITY FOR LONDON TOUR AFTER THREATS FROM A BRITISH STALKER IS TAKEN SERIOUSLY

BEYONCE

Beyoncé has increased security at her show in London on Saturday after fears of a threat from a British stalker.
The 'Grown Woman' hit maker is scheduled to perform at Twickenham stadium at the weekend as part of the 'Sound Of Change' concert and staff have been told to look out for 'fan' Bassey Essien, who is reportedly sending her threatening letters labeling her an imposter.

A source told The Sun newspaper: 'Staff have been briefed on the situation and pictures of him have been passed round. They've been told to keep their eyes open and be extra vigilant.

'Security has been increased on a few engagements now, especially for her UK promo. It is believed similar letters to the ones that Essien sent have been received.'

Beyonce, 31, was previously targeted by the obsessed follower when he met her at a function in London in 2009, trying to give her a book of notes he had made of his religious findings.

Despite claiming he was attempting to help the singer - who is mother to 16-month-old daughter Blue Ivy, who she has with husband Jay-Z - Bassey was sentenced with an anti-harassment order in the High Court in 2011 after several previously failed attempts to get the restriction in place.

Beyonce's spokesman has not yet responded to a request for comment.

The decision to up security comes after Beyonce's bottom was slapped by a male fan during her show in Denmark earlier this week.

Beyoncé was angered when an over-zealous fan slapped her on the ass as she performed on stage as part of her Mrs. Carter Show world tour in Copenhagen, Denmark, on Monday night.

The 31-year-old singer seemed distinctly unimpressed when a rather excitable member of the audience decided to push his luck by reaching up to give her a spank on the derriere as she performed Irreplaceable at the Forum Copenhagen.

And the superstar was so angry at his frisky behavior that she threatened to have him removed from the venue altogether.

The star is due to perform in Stockholm, Sweden, on Tuesday night, before returning to Antwerp to play the gig she cancelled earlier in the month on Wednesday.

On Saturday, Beyonce will return to London to perform at the Chime For Change concert at Twickenham Stadium.

The superstar singer will then kick off the North America leg of the Mrs. Carter Show in Los Angeles on June 28.
