The 'Croydon cat killer' is thought to have claimed 10 more victims in as many days - pushing the total to almost 150 dead pets.

The serial animal killer is believed to have struck various places in south London and Kent recently, having reportedly claimed victims across the country.

Last weekend, two cats were found dead in the same street in Bromley, both from blunt-force trauma injuries.

One of the cats also had its tail removed - a trait said to be typical of the killer.

Other locations the killer is believed to have targeted recently include Petts Wood, Dartford, Wallington and Westerham.

South Norwood Animal Rescue and Liberty (SNARL), which is working with Croydon and Bromley police and the RSPCA to find the killer, is treating these cases as part of the ‘Croydon cat killer’ crimes.

Tony Jenkins, co-founder of SNARL, said: "We've had a case a day for the last ten days.

"The killer is claiming a large number of victims in a short time.

"They've been on one or two other sprees in the past, and this looks like another one.

"Last week we collected two bodies from the same street in Bromley.

"The first cat was found intact, but with a head injury from blunt-force trauma, on Friday morning.

"The second was found in a nearby children's playground with the tail cut off on Saturday morning.

"We believe the killer may have gone to the area on Friday, but been interrupted and unable to mutilate the cat.

"We can't be certain that the cats were killed by the same person, but they were both found with blunt-force trauma injuries to their heads.

"They could have been done by other people, but they fit with the other cases, and police are investigating them as part of the same case.

"We aren't confining this to the south east - cat owners across London need to be aware, keeping cats inside or supervising them.

"People need to be vigilant."

There is currently a £10,000 reward, offered by Peta and Outpaced, in return for information on the culprit who is also dubbed the M25 cat killer.

SNARL has urged cat owners to keep their pets indoors overnight, and said anyone who spots someone acting suspiciously around animals should call police on 101 quoting Operation Takahe.
