One of the centre's employees said electricity was disconnected on Monday.

The centre workers have been holding meeting to in a bid to resolve the problem.
Services that have been affected include registration and issuance of national identification cards and birth certificates, and Kenya Revenue Authority, National Security Service, National Health Insurance and utility bills services.
