Director of Criminal Investigations George Kinoti has described the murder of Dutch tycoon Tob Cohen as gruesome.

He said, "There is no perfect crime that can go undetected."

Adding, "We always know as investigators that there is no perfect crime. A spec to a keen detective will always be spotted. That spec which we actually detect at the scene of the crime, it opened for us the whole world."

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 took a deep breath, closed his eyes then 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's hands and neck were bound before he was murdered. They then hid him in an underground water tank.

"The assassins took their time in plotting the murder," he added.

They later hid him in an underground water tank. The body which was wrapped with many layers of clothing revealed signs of torture before his murder.

The underground storage which was empty had been completely sealed with concrete and covered with bushy wood cuttings.

"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.

The defence team was present when the body was unearthed.
