Shadow home secretary says Tory MPs staged a "mini riot" over Jeremy Corbyn's alleged jibe.
Sajid Javid has backed police over controversial new tactics for stopping moped-riding criminals.
The Home Secretary rejected criticism from Labour, saying "risk-assessed tactical contact" is "exactly what we need".
Scotland Yard last week released dramatic footage showing police vehicles knocking suspects off their scooters.
Senior officers defended the use of "tactical contact", saying it was needed to stop dangerous chases and has helped reduce moped-enabled crime in London by over a third.
Shadow home secretary Diane Abbott raised concerns about the approach.
She said: "Knocking people off bikes is potentially very dangerous. It shouldn't be legal for anyone. Police are not above the law."
But Mr Javid, who revealed in June that his phone was taken in a moped mugging before he became Home Secretary, disputed Ms Abbott's assessment.
He wrote on Twitter: "Risk-assessed tactical contact is exactly what we need. Criminals are not above the law."
Latest figures show 12,419 moped offences were recorded across the capital from January to October - a 36% fall compared with the equivalent period of 2017.
Former home secretary Jacqui Smith has been speaking about her new book 'The Honourable Ladies: Volume 1', which chronicles every female to have sat in the Commons up to 1996.
