Police in Thurrock are issuing a CCTV of a man wanted for questioning in connection with the theft of meat from the Co Op in Aveley in April.
Several joints of pork and beef were taken on three separate occasions between April 11-15.
The suspect is described a white man, aged in his early 20s with short, dark brown hair and was carrying a large blue holdall which he concealed the items in, making no effort to pay.
A number of giant cranes are due to arrive at a new deep-sea container port in Essex. It is the second delivery of cranes to the London Gateway in Thurrock. The first cranes arrived earlier this year and were transported upright on a ship.
They are the biggest ever cranes to be delivered to the UK. They weigh 2,000 tonnes and stand at 138 metres tall - that is two and a half times the height of Nelson's column. In fact, they are so tall it would be possible to roll the London Eye under the lifting arm.
Once the port is fully operational, London Gateway will have 24 cranes on the quayside.
One person has been killed and five people including a child have been taken to hospital after a crash on the M25 near Lakeside in Essex.

They were left shaken but uninjured. They stole a silver ladies Rolex watch and a white Blackberry mobile phone. The men were wearing dark clothing and had their faces covered.

Essex County Council has today pledged its support to the Thurrock Council taskforce being set up following the announcement of the possible closure of the Coryton Oil Refinery.
The site’s administrators Price Waterhouse Coopers announced yesterday that they had been unable to find a buyer for the refinery and were seeking to start negotiations with unions and employers over its closure.
This would mean the loss of up to 500 jobs at the refinery and impact on other companies providing services to the site.
– County Councillor Kevin Bentley, cabinet member for Economic Development
“We have worked closely with Thurrock Council ever since it emerged the refinery was under threat and we remain committed to working with them in the task force they are forming to co-ordinate support and next steps.
“Providing all the help, support and advice needed to those affected is not something that one organisation can provide – it needs to be a partnership approach. This is why we will be continuing to offer our full support to Thurrock Council and others in helping do everything we can to help the workers and ease the impact of any closure of the refinery.”
