Warriors have asked for help in identifying four spectators following complaints that a laser-like device was used to distract players during Saturday’s European Challenge Cup quarter-final at Sixways.

Warriors have studied television and CCTV footage of the match and identified an area in the front row of the East Stand from which flashes of light can be detected.

The seats were not sold in advance but were occupied by four men. None of them are known to Warriors who have asked other supporters to help to name and shame them.

“We are working closely with Harlequins and Premiership Rugby to investigate what is a very serious matter,” said Warriors Operations Director Peter Kelly.

“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.”
