The post prompted dozens of comments from locals who had also noticed the smell, with one person saying the smell promoted them to contact an emergency number.

Heather Dobson, who lives on Oswalds Avenue in Prenton, said the smell was “quite worrying”.
She told the ECHO : "It was really bad. I saw numerous fire engines on Fender Way and it lingered the whole day.
“It smelt of like gas or petrol. It was really strong. Very odd no one knows the actual cause - it was quite worrying."
Another person who contacted the ECHO said: “It smells like there’s been a fuel leak at Shell Ellesmere Port. Friends in Pensby, Upton, Greasby and Caldy all telling me they can smell it.
"It was so bad this morning I thought my house had a gas leak.”
Zoe Neller, who lives on Beechwood, said she was "a little worried".
She added: "I could smell it when we went to Hoylake as well. We couldn’t have the windows open as my whole house stunk of it. It was really strong smelling."
In response to the claims, a spokesperson for Cadent, the gas emergency service in the area, said: “We have has an increase in calls [yesterday], due to a smell that’s carried across a wide area.
"We investigate each one and, as yet, have not found any evidence of an issue on the gas network that could have caused this.
"We do gets incidents like this from time to time. In the past, we have traced it to things like factory discharges, aviation fuel, smells from docks activity, and many other reasons. Our concern in incidents like this is that, in amongst the smells that are not gas, there may be an isolated and unrelated real gas leak."
It is important that if you ever smell gas or suspect a carbon monoxide leak you should call the national gas emergency service at anytime, night or day, on 0800 111 999.
