Police were called in to investigate unusual activity at the offices of utility billing company ARMS yesterday evening, timesofmalta.com has learnt.

The police found the CCTV cameras had been switched off and the alarm was not working.

The police were called in after a tip-off alerted Government officials to “unusual activity” at the offices as Energy Minister Konrad Mizzi was preparing to go public with a statement calling for the resignation of ARMS CEO Wilfred Borg.

The call for resignation was prompted by questions sent earlier in the day by The Times to the Social Solidarity Ministry on complaints by clients who received reduced energy benefit vouchers for April.

An investigation found that the social security vouchers were issued on the basis of wrong information supplied to them by ARMS.

The Social Solidarity Ministry later confirmed that more than 3,000 beneficiaries had received reduced benefits as a result of the mistake and the error will be rectified.

In a statement yesterday evening the Government said the mistake by ARMS followed a series of other mistakes by the billing company that has been dogged by problems since it took over the billing functions of Enemalta and Water Services Corporation.

When contacted this morning Mr Borg insisted he had “no comment to make” on the incident. He has not yet tendered his resignation.
