Inspector General Stella Libongani says the police have advanced in its investigations on the leakage of information from state House and other public institutions.
Ms Libongani says the police will soon close in on the culprits that are responsible for leaking of confidential information.
She said progress has been made but however did not disclose much information to avoid jeopardising the ongoing investigations.
The IG said this in an interview with ZNBC news in Lusaka.
She also said that the service has already started investigating the leakage of the 2016 national budget.
