Detectives were continuing to question a man this afternoon over the murder of schoolteacher Jane Longhurst.

The 35-year-old Hove man was being quizzed at Sussex House custody centre in Hollingbury, Brighton.

He is the same man who was arrested on Thursday and subsequently released without charge.

Meanwhile, pupils have returned to Uplands special school in Hollingdean, where Jane taught music, for the first time since the news of her murder broke.

Headteacher Paul Atkins said the children brought more than 40 floral tributes to class.

A team of educational psychologists were on hand to help pupils and members of staff.

Mr Atkins said: "Many of the pupils have brought in more floral tributes to add to those that have been left at the school in recent days. There are also many very touching messages to Jane.

"The pupils drifted out at lunchtime to read the messages. There was a huge amount of very genuine affection and loss.

"There has been no need to use Jane's classroom and we are not going to make it a shrine. We will at some time make some subtle changes, otherwise it may be difficult."

Jane, 31, disappeared from her home in Shaftesbury Road, Brighton, on March 14.

Police believe she was strangled shortly after she disappeared and her body kept elsewhere before it was dumped and set alight at Wiggonholt Common on Easter Saturday, April 19.

The Argus is offering a £5,000 reward for information leading to the arrest and conviction of the killer.

Motorists have given police new information in their investigation into the murder.

Officers spent five hours stopping more than 700 drivers on Saturday night on the A283 near Pulborough, close to the place where her body was spotted burning.

Detective Chief Inspector Steve Dennis said: "A number of people were able to help us with our inquiries and we were very pleased with the way the operation went."

He said eight motorists gave information which was being prioritised for investigation.

Police are continuing to search for Jane's Nokia mobile phone, her Next purse, keys, denim jacket and red suede shoes.

They also want to hear from other people who were in the Wiggonholt area on Easter Saturday evening.

Anyone with information should contact the Operation Keen incident room on 0845 6070999.
