A sixth Ottawa man has been charged in connection with a province-wide crackdown on child pornography and exploitation of children on the Internet.

Mohammad Nafiz Uddin, 20, was charged with two counts of possessing child pornography and one count of making child pornography available.

Meantime, Ottawa police are still searching for a 29-year-old resident wanted in connection with the case. Alex Mason faces one charge of possessing child pornography. He is still at large.

The investigation netted six others in eastern Ontario last week, including a 17-year-old from Ottawa.
