French prosecutors say two teenagers are in custody following the death of an 11-year-old boy in northwestern France. The boy is reported to have been found on the banks of the Vilaine river in Rennes on Sunday. Prosecutors say his body had a wet bath towel tied tightly around his neck. On Monday, authorities detained a 16-year-old boy at his home, and a 15-year-old girl after she presented herself to police. The Rennes prosecutor Frederic… is cited as overseeing the case, which remains under investigation. Officials have not released further details about a motive or the circumstances leading to the boy’s death, and the investigation is ongoing while police question the suspects in custody. The arrests are part of a murder probe, prosecutors said, and the case continues to be handled by the public prosecutor’s office in Rennes.
