The 17-year-old's mother Erika has used social media to call for her son, who has now been missing for a month.

Something that during the weekend reached a climax with several hundred thousand shares.

Shared by Ingrosso and Zara Larsson

The post has been shared nationally and has received a boost from the fact that most celebrities have shared it.

Among others, Zara Larsson, Bianca and Benjamin Ingrosso, Bingo Rimér and Charlotte Perelli who together reach millions of followers.

The proposal to enlist the help of celebrities to share the call came from a friend's daughter.

- I thought it was a good idea.

People have searched in these areas so much, so I think he might be somewhere else and then publicity is important.

Gives hope

Erika started by contacting a famous comedian who shared the post and then started a chain of shares on the accounts of several celebrities and influencers.

The large participation from the public gives some light in the dark and now the family hopes to get valuable tips.

- We live in fear and then it is easy to lose faith.

This commitment lifts us a little, it gives hope and strength, she says.

Appeals for help

Something that Erika wants is for everyone in the country who has access to some form of surveillance camera to look through the film from the day her son disappeared.

- It will be too big for the police to check it, they can not do it on their own.

But I would like all the shops and gas stations to watch his video surveillance to see if he has been around.
