There has been interference in investigations conducted by the Malaysian Anti-Corruption Commission (MACC), admits a top official from the anti-graft body, but this had never deterred them from continuing their probes.

"Of course, there has been interference... But I will not allow (the) interference to stop our investigation.

"Never happened in my history since I take charge of operations that an (investigation) paper is stopped in the middle of investigations," MACC deputy chief commissioner (operations) Mohd Shukri Abdull said in an official video uploaded by the anti-graft body on YouTube.

While he never explained in the video uploaded on June 6 what kind of interference MACC had to contend with, Shukri continued that under his watch the commission never stopped investigating because of interference or orders from anyone.

"For your attention from the beginning until now, nobody can interfere with our investigation, nobody can instruct the MACC to do this, do this, do this... no. Investigation is our power.

"I will not allow anybody to interfere, I won't allow my officers to stop investigation, once investigated we must complete each investigation paper," he added.

Though Shukri conceded that while the anti-graft body can plow ahead with investigations regardless of interference or instructions, there is nothing he can do when it comes to whether or not the cases they investigated ever see the light of day in the courts.

"I never question the decision to charge or not to charge. This is not my power, you must understand that there is a separation of power between investigation and prosecution," he said in the one minute and 39-second footage.
