Detectives searching for the killer of a Gwynedd woman say they have had a "good response" following an appeal on BBC's Crimewatch.

Ffion Wyn Roberts, 22, was found strangled and drowned on 10 April, in a drainage canal in Porthmadog.

Police are concentrating efforts on tracing all owners of a trainer found near a sluice gate not far from where her body was found.

Det Insp Neil McAdam wants anyone with information to contact police.

He said:"We received about a dozen calls from members of the public centred around what store may have stocked the joggers.

"Most of the calls focused on the source of the tracksuit bottoms and we are looking into the information."

Officers have narrowed their search for the shoe's owner to nine people.

Police believe the items, along with Ms Roberts' handbag, were discarded together as whoever threw them over the sluice gate would have done so with the intention of getting rid of them.

Investigating officers say it must have been a deliberate act because the sluice gate has high fencing around it, so the items would have needed to have been thrown over deliberately, and with some force.

Det Insp McAdam said the joggers were extra large and in blue nylon with two white stripes down each side. They had no branding on them but bore a label inside with the make "Original".

The trainers are also unusual in that they were a size 11 black Ascot brand in the Alaska model.

Det Insp McAdam said: "They are from a batch of 3,100 which came onto the market in December 2009.

"We have eliminated all the people who purchased them via card and now wish to talk to nine people who bought the trainers with cash in north Wales.

"They would have cost between £12-14 and we would like anyone who bought them or knows somebody who has to come forward."

Police also believe they have CCTV images of Ms Roberts 549m (1,800ft) from her home, at 0427 BST, on the day she died.

Meanwhile, another £5,000 reward has been offered for information about the murder.

It brings the reward money for information leading to arrest, charge and subsequent conviction to £10,000.

Ms Roberts' body was discovered by a member of the public, roughly 137m (449ft) from her home on 10 April.

Anyone with information is asked to contact police on 101 (if in Wales), on 08456071001 (Welsh line), 0845 6071002 (English line) or Crimestoppers Wales on 0800 55511.

Crimewatch was on BBC1 at 2100 BST on Tuesday 15 June but can be watched via iplayer on the BBC's website.
