Berlin: German prosecutors are investigating a 14-year-old boy suspected of shooting plastic bullets from a toy gun at the King of Thailand who was cycling near Munich late one evening. The king was not hurt.

The unidentified youth, together with a 13-year-old who is too young to be investigated, is suspected of having fired the gun from a garden or house window at a group of cyclists that included King Maha Vajiralongkorn, a regular visitor to Bavaria where he used to live before the death of his father King Bhumibol Adulyadej, and his entourage.

"A toy pistol, a soft air pistol, was used. First it was fired at a group of cyclists, one of whom was the King of Thailand," said Thomas Rauscher, prosecutor in the southern town of Landshut, on Wednesday. Neither the king nor any of his entourage was hurt.

Prosecutors said the king's household said they had no interest in charges being brought in the case.
