Andy Murray's second-round Wimbledon opponent Stefanos Tsitsipas was booed as he disagreed with the umpire when making a late challenge.
The pair's game ran into the late hours on Thursday and was suspended due to the local council's 11pm curfew on Wimbledon play, meaning they resumed their match on Friday afternoon with Murray holding a two-sets-to-one lead.
After play resumed on Centre Court, Tsitsipas soon hit a return long and then tried to challenge the previous shot. Tsitsipas - who was too late to challenge the call - complained to umpire Aurelie Tourte, who told him firmly that he could not refer to Hawk-Eye.
