He told ITV: “She’s very vulnerable and we’re imagining she’s having some sort of crisis. That’s why we’re so desperate to find her.

“There were some sightings early on and I don’t think she’s left the local area. We have reasons to believe she might be hiding so she might not want to be approached.”

The star has joined search parties looking for Ms Aldridge who the police said they are growing “increasingly concerned” about.

Sussex Police said Ms Aldridge may have travelled as far north as Bignor Hill.

She is described as being around 5ft 4in with grey/blonde highlighted hair and sometimes wears glasses.

Detective sergeant Alan Fenn said: “We would like to thank the public for the information which has been provided to us thus far.

“Our officers are pursuing multiple lines of enquiry and are determined to find Laurel. We would be grateful if residents in the Walberton and Slindon areas could check their outbuildings for any sightings of Laurel.

“Also, anyone who was in the Walberton area on Tuesday morning or has video footage of someone matching Laurel’s description is asked to report it to us.

“The family are being supported by a dedicated officer and being updated with the investigation.”

Crook said the disappearance was “very out of character”.

He said extensive searches were taking place and urged people to look in their back gardens and other places where she may have sought refuge.

“She left her house early Tuesday morning and she’s not been seen since,” he told ITV.

“That’s in the Walberton area where a lot of people are looking in the local woodlands along the roads and stuff like that.

“I’d really like to appeal to people to go out into their back gardens and have a look in places where she she might have taken rest.

“She’s been missing out for three nights – we’re entering the fourth one now (so), we’re obviously really worried.

“If I could appeal to everyone, even if they checked before, check again in likely places where she might have crept in to lay down for the night.”

The public have been urged to report any information of Ms Aldridge’s whereabouts to police by calling 101 if it is non-urgent or 999 if it is urgent quoting serial number 347 of February 14.
