Director of Criminal Investigations George Kinoti has described the murder of Dutch tycoon Tob Cohen as gruesome.
Kinoti spoke moments after Cohen's body was found at his home at Farasi Lane in Spring Valley.
"He was murdered in his residence. It was a gruesome murder. They took their time to kill him," he said.
When asked by journalists what he meant by gruesome, the DCI boss said, "When i say it was gruesome I will give you an opportunity to see for yourself but after the prosecutions, we will share the whole story."
Kinoti said Cohen was bound face,hands, neck before he was murdered.
"The assassins took their time in plotting the murder," he added.
They later hid him in an underground water tank.
"These people are heartless. If its money, domestic issues you can not treat someone that way," Kinoti said.
The top sleuth said CCTV cameras were only installed after the murder of the dutch tycoon.
Kinoti said they are developing the story and two suspects are in police custody.
Cohen's body has since been retrieved from the underground tank which had fresh cement plastered around it.
