The Bebo group has 252 members and has been visited over 1500 times since last weekend, while the Facebook group has 42 members, including Mary’s younger sister Lisa Hendry.

Bebo group member Kimberly Cartmill posted, “Some love for you, Mary, to let you know everyone is thinking about you, hun x. Please get in touch with someone.”

Sami Bremner posted on the Facebook group, “May she return home safe and sound to the love of her family xx.”

The YouTube video has been viewed over 140 times. However, the soundtrack has been removed by Warner Music Group due to its unauthorised use.

The web pages include details from Tayside Police’s appeal for information on Mary’s whereabouts.

The mother of three has not been seen since the early hours of Thursday, February 25, following a night out to Fat Sam’s nightclub with her sister Michelle Rodger.

The sisters met a man in the club who Michelle said pestered them for sex.

The pair were separated after an argument with the mystery man outside Fat Sams led to Michelle being arrested.

Police have released CCTV footage showing her in the company of the man in King Street at around 3am.

Officers received an “excellent response” from a return visit to the city centre on Wednesday night to quiz revellers and taxi drivers, who may have seen Mary and the man the previous week.

Police are studying mobile phone photos taken by Fat Sam’s customers on the night Mary vanished as part of their investigation into her disappearance and have appealed for further pictures from clubgoers on the night.

The mystery man is described as aged between 30 and 45, a slim 5ft 7in, with fair hair and a moustache.

He was wearing a grey roundneck T-shirt, a dark jacket with white reflective piping on the back, and dark trousers.

Mary, who walks with a limp, is 5ft 2ins and has long brown hair and blue eyes. She was wearing a distinctive black and white patterned dress, black leggings, a white duffel coat and flat black shoes. She was carrying a black handbag and a pink inflatable toy.
