VIEWERS were urged to help solve the murder of a woman whose body was found in South Bucks.

An appeal to find the killer of Beata Bryl was made last night on ITV1's Inside Crime, with a fresh plea for anyone with any information to contact Thames Valley Police.

Ms Bryl, who moved from Poland to the UK in 2003, was found dead in Sheepcote Woods, off Hedsor Lane, Wooburn Common, on July 29 2006.

Although her burnt body was found in Wooburn Common 40 miles from her home, police believe she was killed elsewhere after discovering she suffered 22 separate injuries to her head.

The last time the 23-year-old was seen, was on CCTV footage from Leytonstone Tube Station at 11.30pm the day before she was found dead, when she got on the Number 17 train on the Central Line towards West Ruislip.

Ms Bryl was identified when two people recognised her distinctive tattoo and ring, which police released details of when they couldn't work out who the victim was.

She was known as a lively person but friends and family have told police that her mental state had deteriorated and she was constantly in fear of her life.

The police have no major leads and there are a number of different things they hope to find out.

Firstly, if anyone knows which of the possible 22 tube stops Ms Bryl got off at.

Also police want to hear from anyone who saw the waitress in the gap between when she was last seen at Leytonstone station and when previous CCTV footage picked her up at Leyton Tube Station at 3.56pm the same day.

When she was first seen by CCTV cameras, she was wearing a grey tracksuit. But when later spotted, she was wearing a large red fleece and officers want to find out where it came from.

A blue rucksack and a MK One carrier bag she was carrying during the day of her disappearance have also not been found.

When Ms Bryl's body was discovered, she had a distinctive pillow case covering her head, which had hearts and stars on it, which police wish to identify.

Police have increased their reward for information which leads to the killer to £25,000.

Anyone with information should call police on 08458 505 505 or Crimestoppers anonymously on 0800 555 111.
