Slough Borough Council has called on residents to be vigilant after a mystery person chopped down six large trees.
The person - thought to be posing as a tree surgeon - cut down the first tree six months ago. Since then, five more trees have been discovered that have been either completely felled or stripped of their branches ready for felling.
Cllr Joginder Bal, the council’s cabinet member for leisure and environment, said: ‘This damage is not from some kids mucking about and nor is it accidental.
‘Someone is going out of their way to fell some of the large trees in Upton Court Park; these are not broken saplings, it would take a chainsaw to do the immense damage we have seen.’
The council planted more than 150 new trees in Slough last year and said it was ‘unacceptable’ for someone to do this kind of damage.
The council believes the person may be cutting down the trees to sell the wood.
