German prosecutors investigating the slaying of a Chinese student whose body was found earlier this month in an eastern town say they are looking into a possible leak.

The German news agency dpa reported Thursday that some details in the case were known to the public before prosecutors revealed them. The agency also reported that one of the two suspects allegedly involved in the killing is the son of a police officer. The prosecutor's office couldn't be reached for comment.

Prosecutors had said Tuesday the man and woman, both 20, had turned themselves in and said they had met with the 25-year-old female student for consensual sex.

The victim's name hasn't been released. Her body was found earlier this month near her home in Dessau-Rosslau.
