A man fatally stabbed to death in the street on Saturday has been described as a "lovely" person who was "always laughing".
Detectives yesterday launched a murder investigation after Paul Morgan, 39, died after being attacked to his home in Toxteth, Liverpool.
He passed away in hospital after he was found with a stab wound to the chest at 4.30pm on Saturday, Merseyside Police have confirmed.
The Liverpool Echo report that a 21-year-old man who was arrested on suspicion of murder remains in custody for questioning.
A post-mortem examination is due to be carried out, police said.
Detective Superintendent Dave McCaughrean said: "We are appealing for anyone who was in Prince William Street or the surrounding area, and witnessed the incident or saw any suspicious behaviour to please get in touch.
"A man has tragically lost his life and at this stage, we are treating the incident as targeted, however an investigation is now under way to establish the full circumstances."
A neighbour told the Echo: "We don't get anything like that happening round here, not like that at all.
"We're a very close knit community, everyone looks out for each other.
"I think everyone is just in shock to be honest," the neighbour added.
"He was a lovely, just a normal lad. He would never pass you in the street, he would always stop to say hello.
"He was always laughing as well, very friendly."
Another resident said: "I don't know what happened, but my heart breaks for the whole family."
Tributes also poured in online following the death of the popular man.
One said on facebook: "R.I.P Paul. Another good one taken too soon too horrible knife crime thinking of all your family."
Another wrote: "You was liked by many people, another life lost to knife crime when will it end."
