Shoppers were left horrified after a baby squirrel was allegedly beaten to death after wandering into a grocery store.
Eyewitnesses intervened after the animal was reportedly attacked at a store in Camberwell, South East London last week.
One person recounted the alleged incident on social media, saying the "dangerous" individual should be held accountable.
The eyewitness described how "horrified shoppers" witnessed someone "beat a baby squirrel to death" after it "wandered" into the corner shop, My London reports.
A photo of the alleged animal shared along with the tweet shows a squirrel apparently dying under a cloth in a cardboard box after onlookers tried to rescue it and give it water.

"A dangerous man that needs to be held accountable," they told their followers.
According to the customer, other bystanders in the store attempted to save the baby squirrel - but tragically it was too late.
The eyewitness claimed they had informed both the police and RSPCA about the distressing incident.
The RSPCA confirmed on Sunday that they have been made aware of the "upsetting situation" and are asking for anyone with more details to contact them.
In a statement, an spokesperson for the animal cruelty charity said: "This must’ve been a distressing incident.
