The Williams F1 team has confirmed that a further two team members have been released from hospital and have returned home after being treated for smoke inhalation following its pit garage fire at the Spanish Grand Prix.
One member of the team, who suffered burns in the incident, remains in hospital in Spain but is expected to return to the UK for further treatment within the next 48 hours.
A statement from Williams reported that investigations into the cause of the fire are still on-going.
Team principal Sir Frank Williams said he was pleased to have been able to welcome the majority of the team back to the factory on Monday.
"I was pleased to welcome back to the factory the majority of our team this morning. One of our people remains in Spain for further medical assistance, but we are all looking forward to his imminent return," Williams said.
"Everyone at Williams F1 is extremely relieved that this event was contained as quickly as it was and the damage which occurred was, relatively speaking, limited in its nature.
"While the incident was unexpected and definitely most undesirable, it has demonstrated the genuine cohesiveness, camaraderie and spirit of co-operation that exists within the Formula One paddock.
"The astonishing response from the teams and other paddock personnel was immediate, unconditional and overwhelming."
