Makanga urges Kenya Bureau of Standards to intervene in order to contain the importation of fake detectors.
Security within Nairobi has been enhanced in the recent past due to the threat of al-Shabab attacks as Kenya launches a military offensive against the terrorist organisation inside Somalia.
Last month, the Nairobi Central Business District Association (NCBDA) reported that Nairobi city was losing close to Sh100 million daily due to the threat of Al Shabaab.
"Some malls that used to record close to 1,000 people especially in the evening are now facing tremendous challenges. At times now, they only have 30 people, half of whom are security officers," says NCBDA Chairman Timothy Muriuki.
Quoting a survey carried out by NCBDA, Muriuki said there has been a sharp decline in business within the city.
Those affected include malls, bars, supermarkets, and fast food restaurants.
Muriuki challenged business owners to install modern surveillance systems.
He said the association would not allow Nairobi, which is the economic hub in the region to operate like the lawless Mogadishu and watch as mega businesses collapse.
"We are asking the police to stem the proliferation of dangerous weapons through borders. However, as citizens, we must also be vigilant and weed out suspicious people from our midst," he said.
Security training
Echoing Muriukiâs sentiments, SENACA Group Chief Executive Officer Terry Downes urged businesses in the city to take a leading role in helping to contain the prevailing situation through training their personnel on security management.
"A number of security personnel manning business premises in the city do not have a clue of what a bomb looks like," Downess said.
