On 10 October 2009, a Eurocopter EC135 helicopter operated by
Merseyside Police Air Support Groupwas damaged on the ground at its base of
RAF Woodvale. It was believed the purpose of the attack was to disable the police helicopter whilst a serious crime was carried out elsewhere. One police vehicle was destroyed in the pursuit and three people were arrested in connection with the attack.
[24][25] The aircraft was targeted for a second time on 17 May 2010, when masked intruders broke into RAF Woodvale and attempted to set the aircraft alight, the intruders were stopped due to the security improvements put in place after the first incident but some minor damage occurred to the helicopter. It was again believed that this was an attempt to disable the aircraft whilst a serious crime was carried out elsewhere.
