In a tearful Facebook post, Connor’s stepfather John Lewis said, before he went missing, Connor had been denied admission at the nightclub Home so had tried to make his way back to his accommodation.
He urged people to “share the hell out of” the post to help locate him.
“I’m doing this to see if anybody is in Lincoln and knows where he is,” he said.
“If anybody does see him, please reach out to us.”
Connor has short wavy brown hair and was last seen wearing a blue jumper with red and white stripes on the sleeve, blue jeans and white trainers.
