The Plateau state police command has sealed the house of assembly complex in the early hours.
The command is yet to issue an official statement on the action, it is not unconnected to the crisis among members of the house of assembly.
On Monday, a court reinstated Yakubu Abok as the speaker of the house.
Abok, who was impeached in October 2021, had resumed duties with a few loyalists from the PDP and Labour party.
The house is divided into two factions, with one loyal to the current speaker Yakubu Sanda, and the other loyal to the reinstated speaker Ayuba Abok
