Police are investigating a second aggravated robbery in Hawke's Bay this evening.
The latest raid was reported at the Mobil Havelock North service station soon after 8pm, when a lone attendant was confronted by a man said to be brandishing a knife and forced to hand over cash.
The robber, and possibly a second person, fled in a station wagon.
Earlier today, just after 12.30pm, a young male, possibly a teenager, robbed a Pricecutter superette in Napier's Maraenui shopping centre, fleeing with cigarettes and cash after threatening a shopkeeper with a mallet.
As of 9.30pm this evening, no one was understood to have been apprehended in relation to either of the raids, which, involving weapons, make offenders liable for prison sentences up to 14 years.
