A number of people are in police custody this evening after raids in Whanganui today as investigations continue into last week's fatal shooting.
The Armed Offenders Squad, Police Eagle Helicopter and a number of police officers raided the suburb where Kevin Ratana was shot dead last Tuesday.
The tangi for Ratana, a Mongrel Mob member, was being held today and an influx of gang members was expected in Whanganui.
Police boosted their numbers in the city and brought in the Eagle helicopter to provide "support and assistance".
A number of firearms, firearms parts and ammunition are among the items recovered in multiple search warrants that were issued today.
