Thirteenth arrest over Lt-Gen Kuldeep Singh Brar stabbing
A 13th person has been arrested in connection with an attack on an Indian general during a visit to London.
Lt-Gen Kuldeep Singh Brar, 78, was stabbed in Old Quebec Street, near Marble Arch, last week.
A 27-year-old man was arrested in west London on suspicion of conspiracy to murder on Sunday.
Two other men have appeared in court charged with wounding with intent to do grievous bodily harm on the retired officer.
Barjinder Singh Sangha, 33, of Wolverhampton, and Mandeep Singh Sandhu, 34 of Great Barr, Birmingham, appeared at Westminster Magistrates Court earlier.
Mr Singh Sangha is also charged with common assault in relation to Mr Singh Brar's wife Meena.
The suspects were arrested by counter-terrorism officers following searches at addresses in London and the Midlands.
The 13th suspect remains in custody at a police station in south London and the 10 others have been bailed to dates in November.
Following the attack on 30 September, 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.
