Jimmy Mizen had been due to sit his GCSE exams
A teenager murdered at a bakery shop in south-east London has been honoured at the church where he was an altar boy.
Jimmy Mizen, who celebrated his 16th birthday the day before, died from neck injuries which police believe were caused by a shard of glass.
It is thought he intervened when a customer became angry at being asked to leave the Three Cooks Bakery shop in Burnt Ash Hill, Lee, on Saturday.
Tributes were paid to the boy at a Mass at Our Lady of Lourdes church.
Family and friends observed an emotional two-minute silence outside the church on Sunday ahead of the Mass.
Jimmy had six brothers, Danny, 30, Billy, 28, Tommy, 26, Bobby, 24, Harry, 18 and George, eight and two sisters, Joanne, 35, and 21-year-old Samantha.
After the service his father Barry Mizen, 56, said Jimmy idolised all of them and "there was a little bit of Jimmy in each of them as well".
Jimmy was due to finish school on Monday and enrol on an apprenticeship in the housing and maintenance department at Southwark Council.
Mr Mizen said: "There was a sense of decency about him. He was a very straightforward, very uncomplicated young fella.
"Jimmy wasn't afraid of hugs. We loved him and he loved us back. He was very proud of his family.
"I just want to get the right image of Jimmy across. He was a fine, fine young fella.
"We are a very happy family and a very close family. I wanted to bring our children up with decent values and Jimmy had them."
Jimmy had celebrated turning 16 by buying his first Lottery ticket and was due to sit his GCSE exams at St Thomas More Catholic Comprehensive in Eltham in a few weeks.
On Saturday he was in the bakery when a disturbance broke out and it is believed he tried to help.
He suffered serious injuries and died at the scene.
His father told the Daily Mail newspaper that another of his sons, Harry, was with Jimmy when he died.
Victim's friend pays tribute
Parish priest Father Edward Perera said after Sunday's Mass: "I have never seen a parish so numbed and shocked."
Earlier he said: "I met the parents and the whole family... they are numbed and nobody has any words to express the deep shock and the devastation.
"The whole community... is totally devastated because they never thought something like this would happen to anybody in this area.
"It's a quiet place. People are very friendly and very supportive of each other. It's a lovely community."
Conor O'Hehir, 16, who said he was friends with Jimmy since they were three years old, added: "He was a brilliant lad and friend and he's going to be greatly missed.
"It's just a massive shock and I can't believe it."
Det Ch Insp Cliff Lyons, who is leading the murder hunt, said: "This is another tragic incident where a young victim has lost his life.
"There was an argument between Jimmy and the suspect, following which Jimmy was assaulted and he sustained serious neck injuries."
The suspect ran off along Burnt Ash Hill towards Burnt Ash Lane after the attack just before midday.
Jimmy is the 13th teenager to be killed in London since the start of the year.
