Some of our members have posted warnings on the club Facebook page about fishing line being strung up across MTB tracks in Centennial Park.  This is very serious, and I ask anyone that finds any to notify the police immediately and seek advice from them on whether to guard it and wait for police to arrive or to make it safe first, and also let the club know if it happens again.  The potential for serious injury exists.  Remember this in Diamond Harbour?:

I think setting of booby traps like this constitutes the offence “setting a mantrap with intent to injure”, with added offences “injuring with intent to injure” if someone actually gets hurt.  Not sure what the punishment might be, but it would not surprise me if a prison sentence is involved if someone was to be injured.

If I find out more details (where, when, how, who if we are lucky), I will let you know.
