THE search for missing Pat Lamb has been extended across the country.

The 28-year-old was last seen in Maidstone, Kent on a night out on December 12.

His girlfriend, Natasha Morgan, who comes from Ross-on-Wye, has been desperately searching for him since, along with her family and Pat's family.

There are regular updates on the Facebook page, Help Find Pat Lamb.

Her twin sister, Natalie, who lives in Ross, said they have now organised team leaders nationwide to carry out searches for Pat.

Natalie said: "He could be anywhere now if he hitch hiked. We are still going to search central Maidstone but we have to think about every eventuality."

The family believe Pat hit his head during his night out, as CCTV footage shows him rubbing his head and a witness said they saw him hit his head on a Wimpy building. They believe he could have lost his memory.

Pat had been out with friends, but left Bar Chocolate on his own at 11.35pm.

CCTV shows him walking down Gabriels Hill, before going to buy a sandwich in Subway and then shows him outside the bank TSB at 11.59pm.

Footage released on Tuesday shows him in Medway Street car park at 12.23am, although the timing on the footage could be 11 minutes out.

Police are carrying out a fourth search of the River Medway today, which runs through Maidstone.

Natalie said: "They are checking the river again. They checked it not yesterday but the day before. They are not expecting to find anything but they are checking again today because they want to eliminate it completely."

Pat is aged 28, white, 5ft 7ins, slim to medium build, with hazel eyes and short dark hair. He may have grown a beard since his disappearance but was clean shaven/had short stubble on the night he disappeared.

Pat's iPhone last pinged at 1.30am within a five mile radius of Wyke Manor Road, it is then believed to have run out of battery and was switched off from around that time.

Natalie said: "Tasha is really not very good. She is very fragile. She is desperate to find him."
