Drama was witnessed at Kiamaiko business center in Nairobi after police engaged two religious groups fighting over the right to conduct prayers in the area.
The conflict started in the evening when one group sought the intervention of police to stop the other from preaching at night.
After police confiscated the loud speakers, the second group started to throw stones at the other, members saying they had been targeted unfairly.
The clashes left several people with injuries and business people counting losses as their premises were vandalised.
Pupils were also released from school as police lobbed teargas canisters to disperse the rivals.
