Kenyan
police have questioned the bosses of four mobile phone companies over
their firms' registration of activated mobile phone lines.
It followed reports that unregistered mobile phones were used
by militant Islamists who attacked the Westgate shopping mall in the
capital, Nairobi, two weeks ago.
The four were threatened with arrest on Monday after officials accused them of selling unregistered SIM cards.
They denied the allegation.
In 2010, Kenya made it mandatory for all SIM cards to be
registered, a move intended to reduce crime and attacks by militant
groups.
'Police swoops'

At least 67 people were killed
and 175 others wounded in the Westgate attack, carried out by the
al-Qaeda-linked al-Shabab group.
In a joint statement, the chief executive officers of Kenya's
four top mobile phone companies - Safaricom, Bharti Airtel, Orange
Kenya and Yu Essar - said they had given statements to police after
reporting to police stations.
They denied there are active SIM cards which are
unregistered, and said their companies adhere to international security
standards.
But in a BBC interview, Kenya's communications chief Francis Wangusi said police had evidence to the contrary.
"The denial can be there but the fact is that unregistered
SIM cards are still on their networks and police have proven that," he
told the BBC's Focus on Africa radio programme.
Police had carried out swoops in Nairobi on Monday and
Tuesday which showed that "quite a few SIM cards bought in the streets
were activated there and then," Mr Wangusi added.
There were 29 million registered SIM cards and 1.6 million unregistered ones, he said.
Safaricom, whose chief executive officer is Bob Collymore, is the largest mobile phone operator in Kenya.
