An appeal launched after a dog was found hanged outside a primary school has had a 'good response' with officers at the RSPCA working on several lines of enquiry, the animal charity said today.
The dog's death sparked outrage in the community, with several people coming forward offering rewards for information, including a millionaire businessman and Dudley North MP Ian Austin.
Today, RSPCA spokesman Andy Robbins said no-one had yet been arrested, but the charity was working on a number of lines of enquiry.
He said: "There is not much which can be said publicly currently as the investigation is ongoing.
"We did have a number of calls from the public with information and we are grateful.
"There has been a good response."
The RSPCA is leading the investigation along with West Midlands Police.
A passer-by found the animal tied to a railing 15ft above street level in Bishop Close, in the early hours of June 28.
The dog, which is estimated to be between one and two-years-old, was not micro-chipped and it is not known who the animal belongs to.
The dog’s body was removed by the inspector and taken away.
Among those outraged by the attack was a multi-million businessman called Steve Dale.
He offered a £5,000 reward for help in catching the people or person behind the killing.
Mr Dale owns businesses across several industries and lives in Prestbury in Cheshire.
Mr Dale said: "The reward still stands. We are trying to get the appeal publicised so as many people see it and hopefully someone picks up on it.
"I know I'm not the only one sickened by what happened."
Dudley South MP Chris Kelly and Dudley North MP Ian Austin spoken of their horror at the hanging.
Mr Kelly wrote to Home Secretary Theresa May, Justice Secretary Chris Grayling and West Midlands Police chiefs calling for the ‘full weight of the law’ to fall on those convicted.
Mr Austin offered a £250 reward for anyone who provides information leading to a conviction.
Denise Broadman, from West Midland charity Dog Watch UK, said the hanging highlighted a growing problem of pets getting into the wrong hands.
She said: "We are seeing a rise in irresponsible owners.
"It is becoming difficult to track and we're often left with abandoned animals we are left to care for."
