The management of Samoa's National Provident Fund has confirmed that more than 200,000 US dollars was stolen on Monday from the old age pension scheme office.
The Manager of the Fund's Corporate Service, Tagaloasa Uili Matafeo, says police have found a small knife suspected to have been used to open the front door to the office.
Police are questioning staff as well as workers of private cleaning businesses who worked after-hours and last weekend before the money was stolen.
Meanwhile, the Funds provided payments for the five districts affected from the corporation's reserve funds for the scheme.
Tagaloasa says the management is considering introducing new measures for the security of the funds.
At least half a million US dollars is allocated for the payment of the scheme every month.
