India has complained to the Foreign Office after a top diplomat was confronted by protesters at a gurdwara in Glasgow.
The High Commission of India said Vikram Doraiswami had been invited to the place of worship to discuss community and consular issues.
But he left after he was confronted by a small number of activists on Friday.
A Sikh youth group later claimed there was a longstanding ban on Indian officials visiting gurdwaras.
The confrontation follows an international row over suggestions Indian agents may be linked to the murder of a Sikh separatist in Canada.
The incident in Glasgow came during a series of engagements in Scotland by Mr Doraiswami, who is India’s High Commissioner to the UK.
Footage posted on social media shows him being approached by three people after his car pulled up outside the gurdwara in Glasgow’s Albert Drive.
He remains seated in the back of the car while one of the demonstrators appears to make an attempt to open the door.
Another protester can be heard saying: “I think it’s best if you go.”
The diplomat was then driven away.
