Two men were killed after two helicopters collided in mid-air at about noon yesterday, causing one to crash and the other to make an emergency landing. The dead were the pilot of the crashed helicopter, retired navy commander Mohamed Sabri Baharom, 56, and his passenger, businessman Mohd Irfan Fikri Mohamed Rawi, 41.

Former Malaysian Airline System chief executive Ahmad Jauhari Yahya, 66, and his woman passenger, Tan Chai Eian, 51, were slightly injured.

A post-mortem on the two victims was carried out today and the remains of the deceased were handed over to their families for funeral, police said.

Mohamad Farouk urged the public to not spread videos or photographs of the crash on social media to avoid speculations and unwanted comments that might affect investigations.
