Members of Formula One champion Lewis Hamilton's team have been robbed at gunpoint in Brazil.
Hamilton said gunshots were fired and a member of the team had a firearm held to their head when a minibus was ambushed outside Autodromo Jose Carlos Pace circuit in Sao Paulo on Friday night.
The British driver tweeted: "This is so upsetting to hear. Please say a prayer for my guys who are here as professionals today even if shaken.
"This happens every single year here. F1 and the teams need to do more, there's no excuse!"
In a statement, Mercedes said: "Valuables were stolen but everybody is safe and uninjured which is the main thing."
At the time of the robbery, Mercedes' world-championship winning team were returning back to their hotel after preparing for Sunday's Brazilian Grand Prix.
Staff from the FIA, the sport's governing body, and the Williams F1 team are believed to have escaped similar incidents on Friday night.
