A manager at PwC’s office in the Westlands neighborhood in Nairobi, Kenya, died on Friday morning of an apparent suicide, after he fell from the 17th floor of PwC Tower and landed on the balcony of the second floor of the building.

The employee was identified as Stephen Mumbo, according to Peter Ngahu, PwC country and regional senior partner, Eastern Africa.

Mumbo was pronounced dead on arrival at Aga Khan Hospital, according to the Daily Nation.

While local authorities are treating his death as a suicide, they are not ruling out the possibility of foul play.

“There are very strong links that it was a suicide but this is just in theory,” said Kilimani OCPD Michael Muchiri. “However, it is still too early to make a conclusion but we are also looking at the prospect of whether there was some involvement,” he said.

In an email to staff, Ngahu wrote:

Dear colleagues, It is with great sadness that I announce that following the incident reported earlier in Richard’s email, we have lost one of our own, Stephen Mumbo. Steve was a manager in the BRS business unit in Advisory. We are all in a state of shock and disbelief. Our collective grief and sense of loss at this time is profound; but it can not compare to what Steve’s family must be feeling. Our hearts and prayers go out to them. Investigations on the incident are continuing and we will update you when we have further clarity on the incident. Please keep Steve’s family in your thoughts and prayers at this trying time.

According to published reports, Ngahu issued the following statement to the local media:
