71-year-old Scotsman, David Bell Bryson, who is suspected of the murder of an 11-old-boy in Northwestern Bulgaria, has been left behind bars permanently.

Bryson appeared before the Vidin District Court Friday, which ruled that the Scotsman has to be kept in the arrest for the duration of the investigation.

The man allegedly strangled to death the 11-year-old Stanislav Mirchev in the village of Lagoshevtsi close to the city of Vidin on the Danube River. There were suspicions that he might have abused the boy sexually but little conclusive evidence has been reported to this end as of yet.

Bryson told the court in Bulgaria's Vidin that he was sorry about the crime he committed in a state of uncontrolled anger, the Trud daily reported.

Even though the defendant and his lawyer requested that the Scotsman be released on bail, the court decided that he might flee.

Bryson did tell the court that he could have fled before he was arrested, and even inquired about flights to the UK but never left.

The Scotsman was educated in Germany and worked as an aviation mechanic, according to the local authorities.

According to earlier reports citing Bryson's testimonies after we was arrested and interrogated on Wednesday, suspect admitted his guilt and shared details that only the culprit would have known with the police. His confessions came after he failed a lie detector test.

The man has denied having raped the child, claiming that he had become enraged because he suspected the boy of "poisoning one of his dogs."

Earlier, it was announced that the suspect settled in the village of Lagoshevtsi four years ago.

Stanislav was declared missing January 4, 2012, after he went to bring food to a relative, and never came back, and was later found dead near Lagoshevtsi where he lived in together with his big and poor family.
