A 17-year-old boy has been arrested on suspicion of attempted murder over an attack on a woman that left her with 'horrific' life-threatening injuries.

The woman, aged in her 20s is believed to have been attacked at around 11.40pm on Monday in Victoria Park, Leicester, and remains in a critical condition, police said.

The teenager was held on Tuesday evening and taken into custody for questioning by detectives.

Earlier police released CCTV footage in their appeal for a 'clearly dangerous' suspect. It is not clear whether the person in the video has been arrested.

Leicestershire Police described the assault on the woman, who was dragged into bushes in Victoria Park, as truly horrendous and said her attacker would have been heavily bloodstained after the ordeal.

The victim was found near recycling bins around an hour after the attack.

She was so badly injured she has not yet been able to speak to officers about what happened to her.

Police have renewed their appeal for information about the attack.

Detective Chief Inspector Rob Widdowson said: 'This was an horrific assault and has left a young woman in an extremely serious condition in hospital.

'We still need to trace anyone who may have been in the area of Victoria Park late last night or in the early hours of today and who may have seen something which can help us with our enquiries.

'I need to speak to anyone who was in the park between 11.30pm yesterday and 12.40am today.

'You may not think what you saw is significant, but we still want to speak to you.'

He added: 'What is known is that this young woman suffered an extremely serious and violent attack.'

Detectives earlier released CCTV footage of a man they urgently want to trace - it is not clear if he has been arrested or not

The park was sealed off by forensics officers on Tuesday as they searched the area where the woman was dragged into bushes.

Detective Superintendent Neil Castle said the woman had been walking alone across a well-lit section of the park before the attack.

Mr Castle said: 'Whilst crossing the park she was attacked and subsequently dragged into some bushes, where she was seriously assaulted. She sustained horrific injuries.'

Police also asked 'people to stop speculating on social media sites about the precise nature of the attack' as they support the family and hunt for answers.
