A vengeful brother sent a gift-wrapped fake bomb to his sister’s wedding reception sparking an international terror alert, a court heard.

Three days before Hasan Aydemir’s younger sister Hatice was set to marry Menderes Atici, the 28-year-old posted her a hoax bomb from Kentish Town to a wedding hall in Istanbul, Turkey, jurors heard at Blackfriars Crown Court on Monday (October 8).

Inside a WHSmith box tied shut with red ribbon was a clock hooked up to putty-like material shaped to look like cylinders.

A note was attached to the hoax bomb which read: “Leave the package on the table of the bride and groom on 20/03/2011. The package is my gift to Hatice and Menderes.”

The parcel, posted from a UPS depot in Regis Road on March 17 last year, was intercepted by a customs official at Ataturk airport in Istanbul.

The airport was evacuated and the bomb squad called in to deal with the suspicious package.

The device was investigated by a bomb disposal team, chemical experts and a geophysicist and found to be a fake.

Prosecutor Annabel Darlow said: “Had that package reached the intended destination, been taken no doubt as a wedding gift to be happily received, to be opened up at the wedding, it would have caused an enormous amount of fear and panic amongst those who saw the device.

“And it would have resulted in the wedding celebrations being ruined.”

Aydemir had previously threatened to kill his 23-year-old sister if she went through with the wedding, calling her “mentally retarded” on several occasions.

He also told the 26-year-old groom that he would “raid the wedding hall” if the groom did not pull out of the marriage, jurors were told.

Aydemir, from Allington Avenue in Tottenham, denies one charge of sending a hoax bomb.

The jury were shown CCTV of Aydemir posting the package at a UPS centre in Kentish Town.

He told the counter clerk that the package contained a teddy bear, a man’s watch and some sweets, the court was told.

In paperwork left at the delivery depot Aydemir sent the package under the name Cem Guzel and left a fake address.

When Aydemir was arrested on March 23 he claimed to have sent the package on behalf of Mr Guzel, but could not tell police where to find him.

The trial continues.
