- The lorry driver had stopped at Kikopey when three men, armed with an AK 47 assault rifle, accosted him at around midnight.
The suspects later picked three others along the way, before driving towards Nakuru.
Police caught up with the suspects at Free Area in Nakuru as they transferred the stolen goods into a warehouse.
The thugs defied orders to surrender and instead opened fire, prompting a fierce shootout.
Two robbery suspects were gunned down hours after they hijacked a Nakuru-bound lorry on Tuesday morning.
Gilgil Officer Commanding Police Division Emmanuel Opuru said the two were part of a six-man gang found offloading the stolen cargo when police pounced on them.
He said the lorry driver had stopped at Kikopey area to answer a call of nature when three men, armed with an AK 47 assault rifle, accosted him at around midnight.
"They kidnapped the driver, tied him up, drove with him along the highway before dumping him in a thicket," said Mr Opuru.
The Gilgil police boss told the Nation that the suspects later picked up three others along the way, before driving towards Nakuru.
"The driver managed to free himself and report the matter at the Gilgil police station with officers on duty giving a chase," added Mr Opuru.
