Search efforts for the three men killed in the Didcot power station collapse resumed today when the remainder of the building was demolished.

Demolition workers Ken Cresswell, 57, and John Shaw, 61, both from Rotherham, South Yorkshire and Chris Huxtable, 34, from Swansea, were trapped under 20,000 tonnes of rubble when the structure unexpectedly crumbled on February 23.

Four people died in the disaster, but only one body, that of Mick Collings, 53, has been recovered so far. It is still unknown what the causes of the tragedy were.

The building - which was due for demolition when it partially collapsed - was too unstable to be approached and a 50-metre exclusion zone was set up around what is left of the building.

The 11 plastic explosives attached to the structure were detonated and, once, the site is considered safe, teams will be deployed to resume searching the remnants of the plant for the first time since May.

Roland Alford, who is the explosives contractor at the power station, said the four-month delay in completing the demolition was necessary on safety grounds.

He told the Press Association on Saturday: “There has been quite a lot of criticism about delays, questioning why it has taken so long to get to this point, but the fact is nothing like this has ever been attempted before and this is not a simple demolition.

“We have been working on it night and day since March and built up quite a sizeable team of very expert people to work on this, to come up with the charges, the methods of doing it and training.”

Robots of a variety of sizes will carry out some of the work deemed to be too unsafe for humans, a number of which can be controlled remotely using a sophisticated camera set up.

Roads and trains will be halted in the surrounding area while the demolition takes place.

Thousands of people have been filmed descending on New York's Central Park to catch a rare Pokemon on Pokemon Go.

Crowds involved in the mobile gaming craze rushed into the park on Thursday night, after a rare ‘Vaporeon' character appeared in the area.

An onlooker filmed the mass movement in amazement and laughed as people walked past holding their phones in the air searching for the digital creature.

“Look at this! There's a Vaporean that's fallen right there so everyone's running... Oh my God,” the filmer said.

The craze, an augmented reality game which has exploded in popularity, uses the phone's GPS location data to allow players to roam the real world and catch virtual monsters.

A video from showed players swarming another park recently after a wild ‘Charizard' appeared there.

Two Pokemon Go players were apparently so engrossed in the game on Wednesday that they walked off a cliff in San Diego.

Meanwhile fans of the gaming phenomenon were in despair on Saturday when its servers appeared to have crashed. 

On Saturday afternoon, fans posted on social media about how the server was down, the Press Association reported.

Twitter user @Drxpdead_curtis wrote: “The Pokemon go servers are down again what is this hell.”

@gonzorobotics wrote: “i just went on a pokemon hunt but the login servers were down the whole time so i just got a bunch of fresh air and exercise for NOTHING god”.

@vivthediv tweeted: “Headed into central London to catch some cool Pokemon. App doesn't work. Sat in borough market wondering what to do now.”

Pokemon Go has sparked controversy since its launch in the UK on Thursday.

Three students were robbed at knifepoint of their mobile phones while playing the game in Hulme, Manchester, on Friday night just hours after Greater Manchester Police (GMP) warned of the dangers of using the app.

The force had said it was concerned that the app could provide another online avenue for criminals to exploit.
