Police are hunting a suspect after several women were sexually assaulted at Tube stations across a single day.

The attacks are reported to have taken place within hours of each other at Central line stations in Redbridge on October 4 last year.

At around 7.35am that day, a man walked behind a woman going through the ticket barriers at Gants Hill station and grabbed her.

Less than two hours later at Snaresbrook station, a man then sexually assaulted a woman on the overbridge between platforms.

Then, at 12.15pm, a second woman was grabbed and sexually assaulted on the same overpass.
