Residents staying around blocks 165 to 175 at Bukit Batok West Avenue 8 woke up to the sight of blood pools and trails around the estate.
According to Shin Min Daily News, two men were involved in a fight around the area yesterday morning at around 5am.
The fight was believed to have started at block 175.
Thereafter, the assailant chased the victim across five blocks of flats.
The fight left a 600 metre long trail of blood near a car park as well as pools of blood at void decks of blocks 167 and 168. Blood was also seen in the lift of Block 165.
Police have cordoned off the area when reporters arrived at the scene.
Mr Lim, a 40-year-old resident from block 165, told Shin Min Daily News that he heard people arguing at the block's void deck in the wee hours of the morning.
One of the men involved in the fight was believed to have taken the lift up to the seventh floor before mysteriously taking the stairs down to the ground floor thereafter.
