Defenders: Busting the Bad Guys S03E03 - Episode 3

As a spate of acid attacks across the UK make the headlines, officers go undercover to stop retailers selling acid to teenagers. In a 3am stop-and-search operation, police take to the streets around Birmingham to target vehicles carrying fake or potentially dangerous imported goods to car boot sales in the region. And officers catch up with mother-and-daughter letting agents in Cornwall who have pocketed a quarter of a million pounds of other people's money.
