Investigations revealed that in 2016, he was tasked with sourcing quotations from security agencies because Takashimaya's existing security service provider was not able to fulfil the terms of its contract. White Knights Security Services, one of three companies that responded, was awarded a one-year contract starting on Jan 1, 2017, based on Chan's recommendation. Two additional two-year contracts were later awarded to White Knights, one on Jan 1, 2018, and the other on Jan 1 last year. Under the contracts, White Knights was to supply Takashimaya with 18 security officers for the day shift and six for the night shift. If there was a shortfall in the number of security officers deployed, Takashimaya was entitled to issue claims. Investigations revealed that from the start of the first contract, White Knights director Mandhir Singh Karpal Singh faced a frequent shortfall of about three to five security officers for the day shift.
