Former Manchester United and Ireland football star Paul McGrath has used twitter to plead for help in finding his missing son, also called Paul.
Mr McGrath said his family is "very concerned" about Paul and asked social media users to pass on his message.
The 59-year-old, who also played for Aston Villa, said police have been informed of the family's concern for their missing son.
It is not clear when he was last seen.
"Please retweet," Mr McGrath wrote, sharing a photograph of him and his son together.
"Looking for social media help please. Has anyone seen my son Paul in around Hale, Manchester, London or any airports in the past few days?
"Police have been informed but we are very concerned and someone somewhere might have spotted him #thankyou."
More than 26,000 people have retweeted Mr McGrath's message.
