The suspects are being tried for allegedly carrying out an attack that led to the death of a senator.
Six out of 22 suspects arrested over the July 2012 attack that caused the death of a Senator, Gyang Dantong, are being tried at various courts in Plateau and Bauchi States.
Salisu Mustapha, the Media Officer of the Special Task Force STF, maintaining peace in Plateau, told newsmen in Jos on Wednesday that the Force had made significant progress in tracking down suspects of the attack.
The attackers had hit mourners at Masseh Village in Riyom Local Government Area, where they were preparing to bury victims of an earlier attack.
Mr. Dantong and Plateau House of Assembly Majority Leader, Gyang Fulani, died in the stampede as the fear-stricken mourners scurried to safety.
“Since after that incident, there have been all kinds of rumours, especially over the number of casualties and possible arrests.
“We were able to make several arrest and recovered arms and ammunitions,” he said.
Mr. Mustapha said five of the suspects were being tried at a High Court in Barkin Ladi, while another is being tried at the Federal High Court, Bauchi.
He said the remaining 16 suspects were on “open arrest”, adding that investigation to ascertain their level of involvement is still on-going.
The STF spokesman listed arms and ammunitions recovered to include three AK-47 rifles, 14 locally made pistols, one sub machine gun and six locally made shotguns.
Others included a single barrel long gun, 170 live cartridges, four AK-47 magazines and one expended cartridge.
Mr. Mustapha said security had been beefed up around the affected areas and called on the public to use telephone lines of the STF to report any suspicious movement around the areas.
