Police are looking for a gunman who shot dead a night guard in Roysambu area, Nairobi.

The gunman escaped on foot soon after the shooting and nothing was stolen from the victim.

Witnesses said the incident happened this morning at about 4 am.

A witness told police the gunman was wearing a shuka when he approached and shot the victim at close range killing him on the spot. No arrest has been made.

Meanwhile, today marks seven years since masked terrorists burst into Westgate Shopping Mall in Westlands, Nairobi and killed more than 70 people and injured 200 others in a macabre attack.

Security agencies say they have been working round the clock to disrupt plans by the terrorists to launch similar attacks.

In the past weeks, multi-agency teams have been working in parts of Coast and Northern part of the country disrupting the plans. On September 21, 2013, four masked gunmen attacked the mall killing at least 70 people and injured 200 others.

Al-Shabaab claimed responsibility for the incident. This was after a number of warnings of a possible attack. A number of suspects were later arrested over the incident.

Three of them were in court last week for their sentencing but it was pushed to October 5.

The suspects Mohammed Ahmed Abdi, Liban Abdullahi and Hussein Hassan Mustafa are charged with their role in the Westgate terror attack, supporting a terror group and being in the country illegally.
