Measures to protect swans in a town centre after two were attacked last year have been reintroduced.Fencing and CCTV were put in place in April 2024 following a number of incidents where bottles were thrown at two birds.

The safety measures have again been put in by Cleethorpes Wildlife Rescue (CWR) to protect two nesting birds on the River Freshney in Grimsby, North East Lincolnshire.The swans, in the same spot as last year, have laid two eggs and CWR is monitoring the video footage to ensure their safety.CWR volunteers were granted a licence by North East Lincolnshire Council to put in the fencing and CCTV.

The rescue group said thewere considered a success last year, with disturbance of the nest dropping from an average of four a day to fewer than four over the entire incubation period.

They have asked people not to feed the swans on or near the nest as it attracts predators, which puts the birds at risk.

Rare black seal pups have been spotted and photographed by visitors at a Lincolnshire nature reserve.Here's what we know so far.

A fire at an electrical substation in west London, which supplies Heathrow, caused a major power outage at the airport, prompting its closure.It is not yet known what caused the fire at the substation, but Transport Secretary Heidi Alexander said there was no suggestion of foul play as counter-terrorism police investigate.

"The counter-terrorism command has specific capabilities and capacities that mean that they are used to conducting investigations at pace," she said, adding that they were needed as the fire took place next to a critical piece of national infrastructure.Emergency services were first called to Nestles Avenues in Hayes, west London at 23:23 GMT on Thursday.
