The victim, who fell, felt dizzy and numb in his face. His spectacles broke as a result of the initial strike.
The other two officers tried to pull Gavrilov off the victim without success.
As the elevator reached the first floor, an officer ran out to seek help, but the other officer managed to pull Gavrilov off the victim.
Several officers, including some who had arrived at the scene to help manage the situation, pinned him to a wall while another called the police for assistance.
A party of police officers arrived at 5.50am and placed Gavrilov under arrest. He was then escorted to the Police Cantonment Complex.
While there, Gavrilov provided a blood sample, which was found to contain 204mg of alcohol per 100ml of blood.
Closed-circuit television cameras within the elevator captured the scuffle, which lasted about 31 seconds.
The victim went to rest but did not seek medical attention. His broken spectacles cost S$15 (US$12) to repair, and Gavrilov has repaid him this amount.
For causing hurt to a security officer, Gavrilov could have been jailed for up to five years or fined up to S$10,000, or both.
