SPECTATORS face a “lengthy ban” if found to have used a “laser to distract players” during Worcester Warriors’ European Challenge Cup quarter-final against Harlequins.

Warriors have asked for help in identifying four men following complaints that a “laser-like device” had been used at Sixways last Saturday.

Television and CCTV footage of the match have been studied by Warriors and an area in the front row of the East Stand has been identified where “flashes of light” can be detected.

Images have also been released by the club with one showing a green light shining on the ball as Quins fly-half Demetri Catrakilis prepares to take a kick.

The Gallagher Premiership club say the seats were not sold in advance but were occupied by four men.

None of them are known to Warriors but the club have asked other supporters to help “name and shame them”.

Warriors’ operations director Peter Kelly said: “We are working closely with Harlequins and Premiership Rugby to investigate what is a very serious matter.

“We have identified four male spectators who occupied seats in the front row of the central block of the East Stand.

“Those seats were unsold which suggests that the four men in question had purchased seats elsewhere.

“We have clear CCTV footage of them which we are making public in the hope that other spectators can help us to identify and trace them.

“If we can do that, and they are found to have used a laser to distract players, then they can expect to receive a lengthy ban.

“Warriors subscribe to rugby’s core values, one of which is respect for the opposition. Anyone who behaves in an unsportsmanlike manner is not welcome at Sixways.”
