“They went into the house but didn’t have to break the door down.
“I haven’t seen anybody taken out of the house but police officers and forensic teams have been coming and going all night and morning.
“They’ve taken out boxes of stuff and you could see them taking photographs inside.”
Another resident said: “Nothing like this has happened before, it’s a quiet street.“There’s never been any bother at that house.”
