New Delhi and Washington are in the midst of an unprecedented diplomatic row, triggered by the arrest of an Indian envoy in New York.

Devyani Khobragade, the Indian deputy consul-general, was arrested, handcuffed, stripped-searched and then briefly lodged in a cell with drug addicts in New York, on charges that she underpaid her Indian nanny and lied in her visa application - mentioning a much higher wage than she actually paid her.

Reports say Khobragade was required to pay Sangeetha Richards, the nanny, a minimum wage of $4,500 per month under US rules. Incidentally, the Indian government says Khobragade's own salary as a government official was about $4,100.

The Indian government has reacted with fury at the official's "public humiliation". While members of Indian parliament vented their anger, police removed security barricades at the US embassy in New Delhi and curtailed several privileges extended to US staff in India - including free access at airports.

New Delhi says the US acted against Khobragade, ignoring court proceedings pending against the nanny in an Indian court.

India is demanding an unconditional apology from the US. John Kerry, the US Secretary of State, has offered regret.

But emotions are still running high and relations betweent the two global powers have hit a new low.

Al Jazeera has pieced together the sequence of events, that led to the current impasse:
