Specially-trained police dogs searched the area in and around the boy’s home on Monday evening.

A team from the Judicial Authorities’ Forensic Science Unit is also at the scene.

The boy’s family has also been questioned.

It is reported that they gave contradictory accounts of the events surrounding Younes' s disappearance.

His mother said that she left the front door of the family home open when she left the house after arguing with her husband somewhere between 1am and 2am.

However, the boy’s older brother said that little Younes ran away during the row.

The child’s father reported his son’s disappearance to police at around 6am.

The boy is believed to be barefoot and dressed only in a nappy and a pullover.
