Britain's taekwondo fighter Lutalo Muhammad progressed to the quarter-finals of the men's under-80kg category with victory over Tajikistan's Farkhod Negmatov.
The home crowd were in full voice at ExCel as Muhammad, raised just a few miles away in Walthamstow, came out for his Olympic debut.
There was, though, no score between the fighters after the first round.
Muhammad won the European title at the heavier under-87kgs, and soon started to find his range with head shots, but without landing a score against Negmatov's defensive stance.
Both men picked up penalty warnings in the third round, before with 45 seconds left, the Londoner finally connected with a chop kick to the head and moved 3-0 up.
Another sweeping axe kick put Muhammad's lead at 7-1 as he swept into the quarter-finals.
