Nine people have been released on bail after being arrested connection with the attempted murder of an Indian general who was visiting London.
Lt-Gen Kuldeep Singh Brar, 78, was stabbed in an attack by four men in Old Quebec Street, near Oxford Street, on Sunday.
The woman and eight men who have been released were being questioned at west and central London police stations.
Three men who were arrested on Thursday remained in police custody.
The nine who have been bailed are to return to police stations in November, pending further inquiries.
Following the attack, Mr Brar was taken to hospital with a neck wound and has since been discharged.
He led the 1984 raid on Sikhism's holiest shrine, which saw hundreds die when troops flushed Sikh separatist militants out of the Golden Temple in Amritsar in Punjab state.
He is thought still to be a target for extremist Sikhs, but the identity of his attackers is unclear.
