Two more 'letter bombs' recovered

Police hope to speak with suspect Justin McAuliffe about the parcels

The number of letter bombs found during a series of deliveries, mainly in eastern England, has risen to 32, after two more were delivered.

Police said it was thought that both the parcels, sent over the weekend, were part of an original batch.

Luton Police are continuing to search for a suspect they have named as Justin McAuliffe.

His brother, Damian, appealed on Monday for him to turn himself in to the authorities.

He told BBC Look East: "Justin, I just want to say, we love you so much.

"Please give yourself up - we want you back in one piece, we want to hug you."

Damian McAuliffe, who also received one of the suspect packages, said he had reason to believe his brother was suffering from mental problems.

Police say they took a number of tip calls from the public over the weekend about Justin McAuliffe.

Det Supt Nicky Dahl said: "I am delighted that people are coming forward with information and I hope they continue to do so.

"We still need to find and speak with Justin as I am increasingly concerned for his welfare and urge him, or anyone who knows of his whereabouts, to contact the police."

Public warned

Most of the improvised bombs were sent to addresses in Bedfordshire, though one went to Hertfordshire, another to Essex, and one package arrived at a Blackpool pub.

Most of the recovered parcels consisted of plastic food boxes filled with lighter fuel.

Some also contained white powder and others were small white envelopes with trigger devices.

No-one who opened any of the packages was seriously hurt, but police have asked people to use caution when opening their post and to report any suspicious parcels.

Members of the public have also been told not to approach Mr McAuliffe.

The 32-year-old, from Bedford, is white, 5'6" tall, with blue eyes and brown, shaven receding hair.
