A 27-year-old man scheduled to stand trial in state court for manslaughter is facing additional assault charges for crashing a pickup truck into a crowd of pedestrians along Ala Moana Boulevard.

The city prosecutor filed four counts of second-degree assault Wednesday against Alins Sumang, one count for each survivor of the Jan. 28 crash. Three were pedestrians, the fourth was the driver of a vehicle that Sumang crashed into.

Sumang already was charged with one count of manslaughter for each of three other pedestrians who died in the crash. He pleaded not guilty to the manslaughter charges on Tuesday and is scheduled for trial in April.

He has been in custody on $1 million bail since his release from the hospital following the crash. The new charges increase his bail by $25,000. The state has not charged Sumang with operating a vehicle without a valid driver’s license even though he was not licensed at the time of the crash.
