A young Indonesian copywriter, Mita Duran fainted in office after working for 30 hours straight and then died the next day, according to reports.

While cause of death has not been released, local reports blamed her death on long work hours, lack of sleep, and the heavy consumption of energy drinks.

On December 14, Mita posted a complaint on Twitter, '30 hours of working and still going strooong.' Soon after she collapsed and died the following day.

Y&R Indonesia, the company where Mita used to work, said on Facebook that it closed the office on Monday so employees could attend Ms. Diran's funeral.

The company released a statement after news of Diran started to spread. Dear Friends and Colleagues in the Advertising & Marketing community, It is with a heavy heart and deep sadness that we have to inform you we have lost our friend, sister, and work colleague, Mita Diran, earlier this evening. Mita was a talented copywriter with a gentle smile who will always live on in our hearts. We have been to Mita's family residence tonight and expressed our sincere condolences on behalf of Y&R Group Indonesia. It is a great loss and we wish Mita's family the faith and strength in each other in going through this extremely difficult time. Tomorrow, December 16, we will close the office for the day to pay our last respects to Mita at her funeral at Jeruk Purut cemetery at 10 AM. Let us all take a day of silence tomorrow and give Mita's family the support and prayers that they need, from the bottom of our hearts. Sincerely, Y&R Group Indonesia

Social media quickly lit up with condolences, along with messages from advertising staffers urging each other not to overwork themselves and demanding change in the industry.

Mita's last tweet was:

She often used to tweet about her long work hours:

Home before midnight after three long, exhausting weeks. MISSION ACCOMPLISHED. — Mita Diran (@mitdoq) November 18, 2013

Alright, one full week of going home past 2am from the office. Ladies and gentlemen, I believe we just broke a record. — Mita Diran (@mitdoq) November 8, 2013

The more you spend time at the office, the more you consider moving your bed here. Preferably next to the fan. #AgencyLife — Mita Diran (@mitdoq) October 29, 2013

So it's 2AM, Friday night and I'm at the office, nibbling on junk food with 9 other creatives. I'm actually okay with this. #AgencyLife — Mita Diran (@mitdoq) October 25, 2013

Similar incidents of deaths due to overwork and stress have been reported. In May, Gabriel Li, a 24-year-old Ogilvy PR staffer, suffered a heart attack and died at his desk in Beijing. Even 21-year-old Bank of America intern Moritz Erhardt suffered a fatal epileptic seizure in London after reportedly working through the night three consecutive times.
