Gunmen stormed the National Institute for Policy and Strategic Studies in Kuru on Monday night. They killed two soldiers and a police officer stationed at the institution's staff quarters.
The attackers targeted homes of two senior officials at NIPSS. Barrister Nima Salman-Mann, the Acting Director of Studies, and Professor Haruna Dabin, a Directing Staff member, were in their sights.
Handwritten threats had appeared on the officials' doors just days before. One demanded $100,000 from one official; the other asked for N15 million from the second.
The notes surfaced on Saturday. Management was immediately informed of the threatening messages.
A source explained how the assault unfolded that night. Security operatives exchanged gunfire with the intruders before three were killed in the clash.
Local security guards watch the quarters during daylight hours. When darkness falls, soldiers and police take over the protective duties.
"It is believed that the attackers came to the houses of the staff they had earlier sent notes demanding money," the source told reporters.
Dr Osime Samuel heads public affairs at the institute. He acknowledged the attack in a statement Tuesday but withheld casualty details.
Management said the situation was swiftly contained. "There is currently no threat to the safety of participants, staff, residents, or facilities," they announced.
Normal operations resumed as planned at the institute. Security agencies launched investigations into what exactly happened.
NIPSS pledged full cooperation with authorities. Officials promised to release verified details once available.
"The management of NIPSS remains committed to the safety and security of all members of the institute community," the statement read.
SP Alabo Alfred represents the state police command. He confirmed three security personnel died in the incident.
Additional police patrols now cover the area around NIPSS. Reinforcements have been deployed to strengthen security presence.
"The situation is under control and normalcy has been restored," Alfred told journalists Wednesday.
This latest attack joins a troubling pattern across Nigeria. Public institutions, schools, and military formations have faced repeated raids by terrorists and armed gangs.
In May, suspected ISWAP fighters attacked the Nigerian Army Special Forces School in Yobe State. At least 17 police officers and several soldiers perished in that assault.
Security experts worry about the growing sophistication of such operations. Attackers appear to conduct reconnaissance before striking targets.
The threatening notes left at the officials' homes suggest advance planning. It indicates the gunmen knew exactly who they were hunting.
Authorities have not yet identified those responsible for Monday's attack. Investigation teams continue gathering evidence at the scene.
Residents in Kuru expressed deep concern about safety. Many questioned whether security measures at sensitive institutions remain adequate.
NIPSS serves as a premier policy research and training center. The attack raises questions about protecting such vital facilities nationwide.
Officials urged the public to rely on verified information. They cautioned against spreading unconfirmed reports about the incident.
