Hertsmere Police were called to reports of a dog attacking another dog in Hackney Close, Borehamwood, just before 8.45am today (Friday, August 27).
Sadly, a small dog died from the injuries it sustained.
Officers attended and following local enquiries, a German Shepherd dog was located and seized.
A 52-year-old man has been arrested in connection with the incident under the Dangerous Dogs Act and remains in custody at this time.
Inspector Gemma Badat said: “We received several calls this morning from residents who were understandably concerned and upset by what had happened.
“Officers have been in the area for much of today and our enquiries are still on-going.
“The dog believed to be involved has been seized and a man has been arrested in connection with this incident and another incident which occurred on Wednesday, August 25, where it was reported that a dog had attacked another dog, causing significant injuries and injuring a member of the public in the process.
“We’re aware of comments on social media about the circumstances surrounding these incidents and as an arrest has been made would politely request that people refrain from speculating on public forums.”
