THESE are the latest photos released by the police during an acid attack trial, some showing defendants 'loitering' outside a Worcester school.

The first image, taken by a concerned member of the public, shows two of the alleged conspirators, 42-year-old Saied Hussini and 22-year-old Norbert Pulko, outside a city school where they attracted the suspicion of several residents.

The photos were taken on July 13 last year, eight days before a three-year-old boy suffered burns following an alleged acid attack in Home Bargains in Tallow Hill, Worcester.

Three of the defendants - Pulko, Hussini and Martina Badiova - spent hours outside the city school in a black Vauxhall Astra linked to Pulko. At one stage Pulko was observed wearing a plastic or latex glove and was later captured on CCTV following the family, including the child who later suffered burns in Home Bargains, the prosecution say.

During his opening Jonathan Rees QC, prosecuting, told the jury: "In the light of what was to happen and Pulko’s use of plastic gloves on that day, the prosecution suggests that the plan was for Pulko to squirt acid on the boy but he pulled out at the last minute because there were too many people around."

It is the prosecution case that both the alleged acid attack and the failed 'mission' outside the school were organised by the child's 40-year-old Afghan father who cannot be identified for legal reasons.

The second photo is of a woman with the phrase 'Nailed it' and another features a cartoon of a fox with its head in its hands being comforted by a deer. These messages were sent a minute apart seven hours after the alleged acid attack by the boy's father to one of his co-defendants, Jabar Paktia.

All seven defendants deny conspiracy to apply a corrosive fluid.

The defendants are: the boy's 40-year-old father; Adam Cech, aged 27, of Farnham Road, Birmingham who is accused of squirting the acid on the boy; Jan Dudi, 25, of Cranbrook Road, Birmingham; Jabar Paktia, 42, of New Hampton Road, Wolverhampton; Norbert Pulko, aged 22, of Sutherland Road, London; Saied Hussini, 42, of Wrottesley Road, London; and Martina Badiova, 22, of Newcombe Road, Birmingham.

The trial continues.
