The Crime Branch of the Mumbai police arrested an alleged aide of fugitive gangster Ravi Pujari from suburban Goregaon on Wednesday. William Albert Rodricks (21) was nabed from Oshiwara area by the Anti-Extortion Cell (AEC) of the Crime Branch, a police official said.

Rodricks allegedly kept Pujari informed about builders in the area who could be targeted for extortion, he said. He came under the scanner when a Goregaon-based builder got calls from Pujari, demanding Rs 2 crore, said inspector Sachin Kadam of the AEC.
