A CASHIER at BP Marina in South Grafton was subjected to a horror armed robbery on Sunday morning.
Police have heard how three men, one armed with a knife and another with sticks, allegedly threatened and assaulted the male employee before fleeing the service station in the cashier's car with cash and cigarettes.
The incident happened just after 4.30am on Sunday and paramedics treated the cashier for injuries to his face and head.
Police from Grafton have started an investigation into the attack.
Grafton Rowing Club was also targeted by criminals at the weekend.
The rowing shed was broken into through the roller door and four motors were stolen from speed boats in the shed.
The club, which was hit by floods twice at the beginning of the year, estimates the value of the motors to be about $8000.
Arsonists kept emergency services busy over the weekend.
A pile of garden waste was deliberately lit on the grounds of Grafton High School on the corner of Fry and Alice Sts about 10.30pm Sunday.
There was another deliberate fire near the Grafton jail on Hoof St, as well as a wheelie bin fire behind Cotton On at King St about 4.30pm.
There were fires in bins at Wharf St and Cowan St, South Grafton, at play equipment in Alex Bell Park and a mattress was set alight at McKittrick Park.
Police said they spoke to a group of between five and seven youths in the area at the time who claimed they were trying to chase the arsonists away.
A police spokeswoman said inquiries were ongoing.
Garry Reardon, captain of Grafton Fire Brigade, said his crews had been kept busy.
"Fortunately there was no major damage in any of that, but the potential is always there."
The spate of deliberately lit fires is a continuation of last month's nuisance offences, which saw a number of blazes being lit, including one that severely damaged the former Cansdell Corner Store and adjoining property.
