A young dad reported missing told his partner “something dodgy was happening” hours before his sudden disappearance.
Evan Reid has not been seen since getting off a train in Paisley after a night out in Glasgow on Saturday night.
CCTV recorded him on Love Street and New Inchinnan Road, but he has not been heard from since by family and friends.
His partner, Nicole Murray, said the family has been roaming the streets searching for Evan, reports Glasgow Live.
She said: “We are worried beyond belief and shocked. I am just trying to hold it together.
“Obviously we don't know what kind of state he is in, but this is not like him at all. He has no mental health issues, we just don't know what's happened."
“He was in Glasgow on a night out," Nicole said. "He text me to say he was getting the train home.
"He said to me [in a text] there was something happening, something dodgy was happening. I didn't know then that he was on the train already.
"We are waiting on CCTV from inside the train to see if that shows anything.
“We were told [by the people he was out with] he wasn't that drunk.
"He doesn't know anyone in Paisley and other friends and family don't know anyone there, we don't have any connection to Paisley.”
Nicole shares a three-year old daughter with Evan and has no idea why he got off the train in Paisley as opposed to going home to Irvine as planned.
CCTV footage from Gilmour Street station shows Evan appearing agitated as he got off the train.
Evan's friends and family have since travelled to Paisley to look for him and have spent day and night scouring nearby streets and alleyways.
They are also putting up posters in Irvine to see if anyone was on the train on Saturday and may have spotted Evan or others acting strangely.
Renfrewshire police are urging anyone with information about Evan's disappearance to come forward.
Inspector Andy Macdonald said: "This is very out of character and concerns are growing for Evan's welfare, we want to make sure he is safe and well.
"I am appealing for anyone who has seen Evan or who has any information on his whereabouts to contact us."
Evan is described as being around 5ft 8in in height and of slim build.
When last seen he was wearing a khaki green jumper, a black body warmer, dark blue jeans and grey trainers.
Anyone with any information is asked to contact 101 quoting incident 4112 of Saturday, March, 25.
