Two people were left with "life-changing" injuries when a corrosive substance was thrown on to them through their car windows.
Cousins Resham Khan and Jameel Muhktar had been celebrating Ms Khan's 21st birthday before the attack.
Officers would like to speak to John Tomlin, 24, and are appealing for information on his whereabouts.
He has been described as 6ft tall, of stocky build and with short fair hair. He is known to frequent the Canning Town area.

Pretty horrible story. Yet another probable hate crime (per the victim). Seems like we can't go 2 weeks without something horrible happening this year.
It was horrible to see the pictures before and after the acid attack.
