Recorded crime in England and Wales has fallen by 25% compared to the same time last year - with a huge drop in burglary and vehicle crime.
However there has been a rise in domestic abuse incidents, the data shows, as well as a surge in assaults on 999 workers.
The figures, covering the four weeks to May 10, unsurprisingly show shoplifting offences have fallen by half, with most retailers closed.
There has been a 36% reduction in police recorded burglary, a 41% drop in vehicle crime, and a 30% fall in serious assault and personal robbery.
Recorded rape offences have fallen 28%, while shoplifting is down 53% with many retail businesses closed.

But assaults on emergency services workers are up 14% during the period amid a string of incidents where coronavirus has been used as a threat in coughing or spitting attacks.
And police have seen a 4% rise in domestic abuse incidents after fears were raised enforced isolation could see a spike in violence in the home.
The NPCC lead for crime operations, chief constable Andy Cooke, said: "These figures are not a surprise, as the public have largely stayed home during the lockdown period.
"Forces use any spare capacity they have during lockdown to focus on proactively pursuing criminals, completing complex investigations and reducing violence.
"As measures ease, we will bear down crime and do all we can to try and prevent it rising to pre-lockdown highs.
The number of 999 calls made to police forces has dropped by 23% and 101 by 25%.
Currently, around 7.3% of police officers and staff are absent from work across the UK.
NPCC chair Martin Hewitt said: "Policing remains in a strong position and we are not wasting any of the extra capacity this crisis has brought.
"Forces have been able to do more proactive policing and reduce backlogs in complex investigations, which will lead to justice being done for many victims, removing criminals from communities and getting ahead of crime before it happens."
