Engineer was the adjucator of the IPL disciplinary hearing which banned Harbhajan for rest of the IPL matches and slapped a hefty fine of Rs three crore.
"I am sure that BCCI will realise that Harbhajan's punishment has been pretty harsh and I hope for Harbhajan that they are lenient on him. But I can't really comment what the BCCI has to do," Engineer was quoted as saying by a news channell.
The former wicketkeeper also asserted that was "no angel", though he was let off with a warning.
"I don't think Sreesanth is an angel. He is a lovely guy and he has been warned to take it easy... not to go beyond the mark. Harbhajan made a big mistake there, a mistake that has never been made before. You just cannot strike another person," he said.
Engineer also said the video evidence against Harbhajan was so strong that the IPL board had to take action against the off-spinner.
"The footage was extremely incriminating. In cricket there is no body contact like football or boxing. It's something that happened in the heat of the moment and he will be regretful about this through the rest of his life," he said.
