Akinwale Arobieke was convicted of 16 counts of harassment in 2003
A man has been jailed for 18 months for breaking a ban on approaching young men and touching their muscles.
Akinwale Arobieke, 47, formerly of Toxteth, Liverpool, and known as "Purple Aki", was given a Sexual Offences Prevention Order last year.
But two months later he approached a 17-year-old boy and tried to touch his biceps, Liverpool Crown Court was told.
The order was imposed on Arobieke after he was jailed for six years in 2003 for 16 counts of harassment.
His reputation has spread across north-west England where he is known by the nickname "Purple Aki" and is considered by many to be an urban myth, the jury was told.
His latest victim, now aged 18, said he was left feeling "frightened and sick" after Arobieke followed him in Birkenhead in June last year.
He asked the boy how many bench presses he could do.
The boy told the court: "He pointed to my arms and asked if he could see.
"He then lifted his hand towards my biceps and I realised who it was. I backed away and told him I had to go.
"I felt sick and walked away as fast as I could. I went to a friend's house and looked back but he had gone."
Bodybuilder Arobieke had pleaded not guilty.
It was his second breach of the order and his 72nd offence since 1980, the judge was told.
