Police inquiries are continuing into the serious assault of a teenager, who had her head repeatedly stamped on by two girls in an unprovoked attack.

After condemning the attackers at the time, a Lowestoft grandmother has now called for police to follow up on information they've been given.

Tracy Sanderson's granddaughter, 16, was with a friend in Lowestoft about 7pm on Wednesday, February 27, when they were approached by two other girls at The Bleach play area – also known as Harris Park – off Church Road.

As the two girls hit her friend, the 16-year-old intervened, but she was subsequently knocked to the floor.

Mrs Sanderson, 54, said that the offenders jumped on her granddaughter's head 'multiple times'.

With several bystanders witnessing the attack, the police and ambulance service were alerted.

The teenage victim was taken to hospital and later discharged, but still 'very disorientated' she returned to hospital two days later and was told she had a concussion.

Mrs Sanderson said: 'In a way she was lucky. To have your head jumped on multiple times, it could have been so much worse.'

But almost a month from the assault, it is believed that the attackers and some witnesses have yet to be questioned about the incident, leaving the 16-year-old girl and her family concerned.

Mrs Sanderson said: 'This was quite a serious assault, but the investigation is not being able to gather momentum in any way which is really bad and not good for my granddaughter.

'She is still finding it difficult as she does not want to be on her own and wants to be around people.

'She is still not comfortable with going anywhere on her own and although she is now back at school it has changed quite a bit for her. She was off school for a week, but being in the middle of her GCSEs she has to be in school.'

With her granddaughter having had a couple of panic attacks since the attack, Mrs Sanderson added: 'She is trying to come to terms with it and she is a very courageous girl.

'She had the courage to give this really important information to the police – and that information needs to be followed up.'

A police spokesman said: 'Suspects have been identified and enquiries are progressing.'
