Officers are returning to Church Road this evening to talk to residents a week after Oliver Tetlow was killed by a hail of bullets in what they believe to be a case of mistaken identity.

In a statement, Pamela Humphrey, Mr Tetlow’s mother, said: “It wasn’t a killing, it was an execution. I miss my son very much. Our family miss him very much; he was loved and is still loved.

“The only way to stop this happening again is for people to come forward and provide information that will see the killer and accomplices brought to trial as soon as possible. These people claim to have no fear but they so have one overriding fear, and that is of being caught. Let’s reflect that fear by passing information that will see them being caught.”

Mr Tetlow’s killer used a ‘high-powered weapon’ believed to be an ‘Uzi’ before fleeing in a dark coloured car with blacked out windows.

Detectives investigating the killing are looking into claims the murder is gang-related after a video showing gang members from the Church End Estate taunting their rivals in South Kilburn was posted online.

The footage shows a man holding a gold watch and several pieces of jewellery which is believed to have been robbed from a South Kilburn rival.

DCI Mark Lawson, said: “This evening my detectives will return to the scene along with local officers, to speak to people and encourage more witnesses and anyone with information to talk to us.

“Today, I am specifically appealing for the driver of a white transit van that was parked in Church Road, close to where the shooting took place to come forward. I believe the driver was sat in the driver’s seat at the time and it is possible they could have witnessed something.

“I would again like to reassure anyone worried about coming forward that they will be treated with the utmost sensitivity.”

Seven people have been arrested and bailed to return.

A 19-year-old man was arrested in Harlesden on suspicion of robbery today and bailed until early May which follows the arrest of an 18-year-old man in Colindale on suspicion of robbery on Monday.

A 23-year-old and 24 year-old were arrested in Colindale and a 21-year-old in Southall on suspicion of murder on Monday and bailed to return in mid-June.

This follows the arrest of an 18-year-old in Harlesden on suspicion of robbery two days after the killing on March 11 who is bailed until early May and a 29-year-old man arrested on suspicion of murder in the Shepherd’s Bush area the same day, bailed until mid-June.

Anyone who witnessed the incident or has any information is asked to contact the incident room on 020 8358 0200 or contact Crimestoppers anonymously on 0800 555 111 or at crimestoppers-uk.org.

PAMELA HUMPHREYS STATEMENT IN FULL

On the evening of Wednesday 9th March, my son Oliver Tetlow was shot and killed.

It wasn’t a killing, it was an execution.

This country holds itself up as model of democracy with fair and open trials before judgement is passed. It is transparent so people can see justice being done, and done fairly.

An execution of this sort doesn’t fit it with the model of this country, and as such it was illegal at any level.

My son was an innocent bystander and was ‘accidently shot’. It is a heartbreaking tragedy that any mother or parent will understand. I hope that everyone reading my plea will consider this: Next time it could be a member of your family, or even a close friend.

The only way to stop this happening again is for people to come forward and provide information that will see the killer and accomplices brought to trial as soon as possible.

These people claim to have no fear but that do have one overriding fear and that is of being caught. Let’s reflect that fear by passing on information that will see them being caught.

Providing information in this case isn’t a matter of honour, these people do not respect the honour or safety of people, not of their kind. They believe they are a law unto themselves.

Please, please help me and yourselves to bring the killer of my son and the accomplices of the killer to the full justice of this country.

My son’s death will not then have been in vain, you may save some innocent person, or the life of one of your family or close friends.

I miss my son very much. Our family miss him very much; he was loved and is still loved.

I hope you’re never put into the awful situation that we find ourselves in right now.

Please, please help me, help my family and in term help provide safety for yourselves and your families in helping us.
