A SLEAZY teacher who admitted making crude and inappropriate comments to nine pupils avoided jail yesterday.

Nat McMullen left the girls aged 12-16 “extremely uncomfortable” while working as a maths teacher at a school in Glasgow’s East End.

The 70-year-old made remarks about wanting to pay to look up a teenager’s skirt and pinned another girl up against a wall.

Glasgow Sheriff Court heard some girls broke into tears.

McMullen returned to the dock having pleaded guilty to conducting himself in a disorderly manner, repeatedly making gestures, uttering comments of a sexual nature and committing a breach of the peace.

His lawyer claimed McMullen, of Hamilton, Lanarkshire, had been “trying to build a rapport” with ­pupils to get “street credibility”.

Sheriff Alan Findlay told the shamed OAP: “I am a bit disappointed in your attitude, but I will deal with this with a supervision order.”

The sheriff imposed the two-year community payback order which will see McMullen monitored by social workers. He was also placed on the sex offenders’ list for the same period of time.

The court earlier heard how ­McMullen retired in 2007 before returning to work in 2014.

He told a 16-year-old girl in front of her class: “I would pay 20 quid to look up your skirt.”

McMullen also pretended to spank another girl and pinned a third girl against a wall.

He suggested a female pupil who was late to class should sit on his knee, which made her feel “extremely uncomfortable”.

McMullen cornered a 12-year-old girl in a corridor and at one point touched her hip with his left hand to restrain her.

In a police interview, the girl said: “I wanted to move away from the wall and he wouldn’t let me move at all and that’s when I started crying as I got a fright and I froze.”

A 14-year-old was asked by McMullen to take off her shirt in one of his maths classes. He also quizzed the girl where she bought her underwear.

A 15-year-old pupil reported McMullen came from behind and squeezed her.

A number of complaints were made by sickened pupils and parents. McMullen was quizzed and claimed he felt “unwell” before later resigning.
