The issue of drinks spiking has been one West Yorkshire Police has been alive to, recording and investigating  for a number of years now.  Following the increase in  Drink Spiking and Spiking through Injections offences, West Yorkshire Police  have responded quickly with partners and created a dedicated multi-agency co-ordinated response under Operation Jeanhaven. 
 
This approach is supported by Health, the dedicated Community Safety Partnerships, Education providers and other key partners including licensing and pubs, clubs, and bars and across the night-time economy in Leeds and West Yorkshire. The aim is to safeguard the public and protect against this offending and bring those responsible to justice.

Offending can take place against women and men in a wide variety of scenarios including domestic situations in which an attempt is made by a person to harm another known to them, and in the night-time economy. This kind of offending in the night-time economy has of course come to prominence as part of the wider debate around violence against women. The issue of women’s safety is rightly a key national and local issue and we do understand the genuine safety concerns that women have.  
 
All offences of spiking that have been reported are recorded as a crime in line with the force’s crime recording policy and then investigated.  West Yorkshire Police has been working closely with fellow agencies including NHS colleagues, the wider public health arena and local authorities to better understand offending, including spiking by injection, and pursue available investigative opportunities.  
 
Crimes recorded are of course subject to further investigation, reclassification and cancellation, and may therefore change over time.  
 
We also of course continue to work alongside partner agencies and licensees to advise users of the night-time economy about the issue and remain absolutely committed to doing everything we can alongside our partners to make the county a safer place.
