PETALING JAYA - Shoppers and movie-goers at the 1 Utama Shopping Complex had their outing cut short when a sudden blackout hit the mall.
Disgruntled netizens posted photographs of the shopping mall shrouded in darkness.
Engineer Kensim, 29, said he only managed to watch the first five minutes of the movie X-Men: Days of Future Past when the screen suddenly went blank.
"We waited for about 15 minutes in the cinema before someone came in and told us that the shopping mall was experiencing a blackout.
"Many people demanded refunds for the movie but we decided to leave," he said.
During the incident at 3.15pm, many roads near the mall were congested as shoppers scrambled to exit the mall.
Student Lim Xu Fern, 16, said she felt it was best to head home as "a lot can happen in the dark".
"I was worried that the security here might be compromised due to the blackout," she said.
Her friend, Naomi Kung, also 16, said she was watching a movie with Lim and another friend when the blackout happened.
Restaurant manager Elaine Chia said she was upset that business was interrupted.
"Since it is a Sunday, there were many patrons but most of them decided to leave immediately. It became very hot and humid as air-conditioning was cut off," she said.
A spokesman for the complex said the incident was not caused by the mall's internal electrical system.
"Some other parts of Bandar Utama also experienced the power disruption," he said.
The power was gradually restored at about 4.55pm using a generator.
When contacted, Tenaga Nasional Bhd said they had received many complaints from residents in surrounding residential areas which have also been affected by the blackout.
As of 5.30pm, it said the cause of the power failure had not been determined yet.
