A doctor charged with murdering 15 patients in three years may have killed even more, police fear.

Described as having a ‘lust for murder’, 40-year-old Johannes M. was first arrest in Berlin, Germany, last August on suspicion of killing four people.

But the number of alleged victims rose after the bodies of former patients were exhumed and examined.

Johannes M. has now been charged with 15 murders.
