When Khalid's family moved into the villa this summer, the sellers said that an old man can come to visit sometimes.

Since the move, the man has come several times a week and sometimes several times a night.

The children become frightened and the family's sleep is affected.

Now they want the man to get help as quickly as possible.

- He knocks on the door, presses the bell and can come 4-5 times a night from midnight to three in the morning.

If we do not open the front door, he walks around the garden and knocks on windows, says the father of small children Khalid.

The man's friends used to live in the house

The man lives alone near Khalid's villa.

He comes with his walker at all possible times, but the nightly visits are the big problem.

The man with dementia has previously had friends who have lived in what is now Khalid's villa and can come for "coffee, cake and some company" as he says.

He thinks his friends are still living in the house.

Khalid is afraid that the man will get into trouble and injure himself in the cold.

- He can stay here outside the house for hours.

We help him back to his house, but after five minutes he's back here.

I'm sorry for him, because he's an old man and he really needs company and help, says Khalid.
