Investigators with the Integrated Homicide Investigation Team have released the victim's name.
They say the death remains suspicious and the case is still very active.
UPDATE: Maurine Arogie had just started school at Kwantlen Polytechnic University this year, CTV News reported. She was voted student of the month at Guildford Learning Centre last year.
A 23-year-old man was taken into custody shortly after Arogie fell from the 26th floor of the north Surrey building.
The man was released Thursday and charges have not been laid.
Arogie's death, barely an hour after midnight on New Year's Day, marked Surrey's first homicide of 2014 and followed a record-high 25 murders in that city in 2013.
