I was going to put this in Wildlife Highlight of the Day, but then thought better of it.
A colleague has just informed me that as he entered the bottom of the Innocent Tunnel on Friday afternoon, in addition to the usual pile of empty bottles and Party 7s, there was a huge cloud of flies around a pig's head. Being a numpty, he didn't report it to anyone.
I've just reported it to the local team. Poor bloke having to send a team out to collect a pig's head. He says nobody else has reported it over the weekend, so either it's still there, or someone's taken a shine to it and taken it home.
