There was pandemonium at the headquarters of the National Health Insurance Scheme (NHIS) on Monday morning as suspended Executive Secretary, Professor Usman Yusuf, arrived the premises in company of heavily armed policemen.
Union leaders and workers who attempted to prevent Usman from gaining entry were teargassed by policemen numbering almost 50.
Yusuf was suspended last weekend by the NHIS governing council which also set up a panel to probe allegations against him.
He was previously suspended by the Minister of Health, Isaac Adewole, in July 2017 over alleged gross misconduct and fraud but was in February controversially reinstated by President Muhammadu Buhari.
