Police are appealing for help to find a St Helens pensioner with dementia who has not been seen for several days.
Jack Platt, also known as John, was last seen at 8am on Saturday on Stratton Drive in St Helens.
The 88-year-old is described as white, around 5ft 6ins tall, of medium build and with balding hair.
Mr Platt, who suffers from dementia, was last seen wearing a checked shirt, grey jacket, trousers, glasses and a brown flat cap. It is believed he was carrying a walking pole.
Mr Platt has a strong St Helens accent and has links to the Rainhill area.
Teams of specially trained officers, as well as the National Police Air Service and Merseyside volunteer search and rescue team, have been looking for Mr Platt over the weekend, but are urgently asking the public for their continued help.
Ch Insp Gary O'Rourke said: "If you see someone matching Jack's description, please let us know so we can help bring him home safely.
"We are all understandably really worried and would appeal to anyone with information to get in touch. Jack is a local man with many memories from the St Helens area so we're hoping we'll find him as soon as possible."
Anyone with information is asked to contact police on 101 or via @MerPolCC on Twitter.
