An explosion has been reported near Odeon Cinema, Latema Road at the Nairobi Central Business District.
One person sustained injuries from the explosion, and has been rushed to hospital for treatment.
Police have confirmed the explosion, adding that it could have been caused by an improvised electronic device.
Members of the public have been urged to stay away from the scene as bomb experts comb the area.
It is still not clear how the explosion occurred, but reports on the Standard indicate that an unknown man sought the services of a trolley pusher to carry a box, which is suspected to have contained the suspected explosive device.
The Standard reports that Nairobi Police boss Philip Ndolo has confirmed that the client who hired the services of the trolley pusher disappeared after the explosion.
The explosion comes barely two weeks after criminals attacked Nairobi's DusitD2 Hotel leaving 21 people dead.
