Police figures show crime has fallen by three per cent in the last three months - but shoplifting and theft is on the increase.
The data - released by Lincolnshire Police and Crime Commissioner Alan Hardwick in his quarterly force performance update - reveals a five per cent rise in theft and shoplifting crimes compared to the same time last year.
This is equivalent to 443 extra crimes.
Mr Hardwick, who holds Chief Constable Neil Rhodes to account, said: “The force is actively tackling this issue and I continue to closely monitor and review the situation.
“Increases have also been seen on a national level.”
The number of sexual offences is also higher this year.
There have been 55 extra incidents - a 12.7 per cent rise.
Mr Hardwick said: “It is thought that successful campaigns such as the force’s ‘no means no’ campaign may be raising awareness and reporting.
“There has been an increase nationally and this is thought to be partly related to the ‘Yewtree effect’, whereby greater numbers of victims of sexual offences have come forward to report historical offences to the police.
“I continue to push for improved crime resolution rates in this area.”
But overall, Mr Hardwick is happy with the latest results - the three per cent drop in crime is equivalent to 853 fewer incidents.
He said: “Overall in this period, the force, has once again, returned excellent reductions in recorded crime.”
And there have been fewer incidents in several key areas highlighted in the police and crime plan.
The data shows burglary and dwelling crime is down nearly 14 per cent, anti-social behaviour is down 18 per cent and violence against a person causing an injury is down 9.5 per cent.
It also reveals a 5.9 per cent reduction in the number of people killed or seriously injured on the county’s roads.
This means there have been 23 fewer victims.
Mr Hardwick said: “The force is currently on track to meet the joint target agreed by the Lincolnshire Road Safety Partnership.”
The next update is due in April.
