Police have stepped up patrols after a spate of arson attacks at a primary school.
Arsonists targeted Clements Community Primary School in Greenfields Way.
The first incident took place between 4.15pm and 4.30pm on Saturday, August 1.
Arsonists caused extensive damage to a wooden pergola at the rear of the school building.
It is believed wood was pulled off the structure and then burned nearby where police found evidence of a fire.
Arsonists struck the school again between 11.45pm and 11.55pm on Monday, August 3.
This time, a wooden picnic bench was set alight.
The next day (Tuesday, August 4), a public bench on the corner of Clements Close and Clements Lane was deliberately set on fire.
A police spokesman said it was fairly probable the same people were responsible for all three attacks and police are keen to speak to anyone who may have information about any of the incidents or those involved.
Patrols in the vicinity of the school are being stepped up, with officers also contributing to an increased presence in other parts of the town in a bid to catch those responsible and to deter those who may be thinking about committing similar offences.
Anyone with any information about any of these events should contact Haverhill police on 101, quoting crime reference HH/15/1929, HH/15/1951 or HH/15/1960 (in order of the occurrence of the incidents).
