Mansfield sex attack: TV appeal gets "significant" new lead
A TV appeal has lead to a "significant" new lead in the hunt for a violent sex offender, police have said.
The case of a 32-year-old woman, attacked on Racecourse Park, Mansfield, in September last year, was featured on BBC Crimewatch on Thursday night.
She was beaten and subjected to a 20-minute ordeal.
Officers, who also released an e-fit of the suspect, said they were examining a wealth of new information but one call had seemed particularly important.
The victim still "mourns the loss of her life as she knew it", they said.
The attacker was described as aged about 20, between 5ft 8ins and 6ft tall, slim and clean shaven.
He was wearing light coloured trousers, a dark hooded top and a pair of white shoes with a striped elastic detail on the side.
Det Ch Insp Mel Bowden said they were still appealing for more help: "If you know someone who wore or still wears shoes like the ones pictured, if you recognise the person pictured in this e-fit image, or if someone you know came home that night with blood and dirt on their clothes, dial 101."
