Star Trek convention marred by phaser violence
A stallholder selling Leonard Nimoy books was left temporarily inert after being hit on the thigh by a blast of concentrated energy.
Onlooker Tom Logan said: “Someone was trying to get William Shatner to sign his name on their face in Klingon.
“People in the queue were getting restive and a bolt of light was fired. Luckily a security guard was able to disarm the culprit with a Ferengi energy whip.”
