A 14-year-old American boy, Aydin Brown, has gone missing after disembarking from the cruise ship 'Caribbean Princess' in Warnemünde, Germany.

The teenager, who has mild autistic traits, left the ship around 7 AM on Thursday following an argument with his grandmother.

Police have launched an extensive search operation, utilizing sniffer dogs and reviewing surveillance footage.

Aydin's family fears he may have been lured away by a stranger.

Authorities are also seeking a witness, described as a man in his early 20s with a distinctive long braided ponytail, who was last seen with Aydin.

The police are investigating possible connections to the gaming community, as Aydin may have made contact with local gamers.
