The matter is being investigated following established guidelines as set down by the company‚ with the assistance of the mall’s security and local authorities‚" the company said.
"As an organisation‚ we would like to reiterate that customers be vigilant at all times‚ and to safeguard their personal belongings. This is communicated in all areas of the cinema complexes‚ via signage‚ posters and on-screen adverts‚” the company continued.
Customers blasted the cinema for the statement‚ saying there was nothing the couple could have done to prevent the incident.
"They got robbed! By a group of men in the cinema surrounding them! How exactly were they supposed to 'safeguard' their belongings?? You’re making this their fault when it was not‚" replied one patron.
