CANCUN, Mexico (AP) -- The body of a Mexican man has been found in a lagoon in the resort city of Cancun, after crocodiles apparently dragged him under water.

Authorities say the man died over the weekend while swimming in an area marked with signs warning about crocodiles.

The director of the city's forensic examiner's office said Monday that the autopsy found crocodile bite marks on the man's arms and shoulders.

But Jose Lugo said those bites weren't fatal, and that the cause of death was drowning.

The victim was identified as 31-year-old man from central Mexico who had recently arrived in Cancun, intending to live there.

The Nichupte lagoon is located just behind Cancun's hotel strip. The lagoon is ringed by restaurants and docks, but swimming is discouraged.
