Lingadzi police in Lilongwe have arrested four suspected armed robbers who have been terrorising and robbing households in New Area 43 in the city.

Central West Police Spokesperson Foster Benjamin says last night several members of the gang invaded a construction site in the area where they were attempting to steal materials.

Benjamin says the four, together with other members who are currently on the run, were nabbed by police who were manning the scene after being tipped off about the planned robbery.

He says one suspect, James Ngwenya, was shot in the stomach as he was attempting to snatch an officer's rifle but is currently receiving treatment at Kamuzu Central Hospital.

"Prior to this, the four suspects, and others at large, had been targeting the site, stealing building materials in the process. The owner sought police intervention to secure her premises," disclosed Benjamin.

"In the middle of the night, the gang invaded the place and first threatened the premises' watchman and his wife with pangas. Immediately, two police officers manning the same yard rushed and fired warning shots, but to no avail," he added.

He has identified the other three as Precious Malipo, aged 20; Duncan Charles, aged 21; and Khumbo Makwinja, 27, all from Mgona township.
