Jordan Bartlett, 19, from Cippenham, was reported missing by a concerned friend on Friday last week and worried relatives of Gurdip Kang, 49, from Slough, grew concerned after he left home on Saturday morning without saying where he was going.
Mr Kang, a plumber, was last seen by his wife, Amarjit, just after 7am on Saturday. The couple had returned home from a Sikh temple, Gurdwara Sri Guru Singh Sabha, in Sheehy Way, Wexham, when the father-of-two walked out of his home in Shaggy Calf Lane without saying a word, leaving his mobile phone behind.
His car, a maroon Vauxhall Astra, was later discovered by the Jubilee River in Slough by police.
Family and friends are growing increasingly concerned for the welfare of the man described as a 'popular', 'bubbly person'.
His heartbroken wife, Amarjit, asked The Observer to publish this personal plea. She said: "Gurdip it is now six days since you have left us and we are all so worried about you.
"We are missing you so much and want you to come home and give us a hug or just call to let us know you are safe and well. Sam and Pam [his children] are desperate to see you."
Older brother, Kuldip, added: "We are naturally very upset, this is a very emotional, stressful time. We are just concerned for his safety. All we want to know is that he is safe."
Mr Kang is believed to be wearing a black turban, a navy fleece jacket, a white polo shirt and black trousers.
As The Observer went to press, police said that Mr Kang's family was offering a reward for information leading to his safe return.
Teenager Jordan, who works at Asda, in Cippenham, was last seen by his mum, Julie Stent, and step-father, Kenny, on Friday morning. The former Westgate School pupil was getting ready for work when the couple left to visit family in Huddersfield.
Mum Julie, 45, told The Observer: "The first we knew about it was when I called the house at 9pm and a police officer answered. They'd broken in to see if he was here."
The teenager made contact with a friend, at around 4.30pm, who was concerned for his welfare and alerted police. Jordan had posted troubled messages on his Facebook page, but has not been seen since.
Mrs Stent said: "We have no idea where he could be. We love him and just want to know he is safe. He means the world to us. It has been hell.
"Jordan, if you need help we will help you. Just come home or call the police so we know you're safe."
Worried family and friends have set up a 'Find Jordan Bartlett' Facebook group and have been handing out missing posters in the town. Brentford Football Club has also posted an appeal on its website for information to trace the missing fan.
Jordan is described as white, around 5ft 8ins, slim with short, black hair.
