Police are investigating allegations made by a young man who says he was tortured over the weekend by army soldiers patrolling a Rio de Janeiro slum.

Inspector Jose Costa da Silva tells the O Globo newspaper there is "no doubt" that the 22-year-old man was "tortured."

He says either eight soldiers on duty in the Vila Cruzeiro slum or local drug dealers tortured the man.

The newspaper says medical exams show that the victim's right arm had been fractured and that both his wrists were bruised apparently by handcuffs.

Requests for further details on the case went unanswered.
