His wife has gone into hiding with their five-year-old son, according to UK media reports.
The envoy allegedly attacked his wife after a row at their home in north-west London. He claimed diplomatic immunity when questioned by police.
'Christmas tree row' Britain's foreign office had asked the Indian High Commission in London to waive the official's immunity.
A BBC correspondent in Delhi says the incident had become a source of embarrassment for the Indian government.
The diplomat was involved in a fracas with his wife on 11 December at their home in the upmarket Golders Green area.
The argument was reportedly started when the envoy found a Christmas tree in the house that had been given to them from one of his wife's relatives.
Neighbours called police after hearing raised voices from the house. The envoy's wife was found with a bleeding nose, Britain's Mail on Sunday newspaper reported.
