The last missing person has been pulled from the train wreckage, three days on, bringing the number of dead in the Buenos Aires train accident to 51.

At the station, angry protesters started gathering as police re-opened the search for the 20-year-old victim.

They demanded an explanation for the accident.

Their numbers swelled quickly.

Chanting anti-government slogans, some vandalized turnstiles and set fire to signs and debris in the station.

Riot police put out the flames and contained the hostile crowd, taking some demonstrators into custody.

Many criticize the government over safety issues and the poor quality of trains which lead to dangerous travel conditions.

It's not the first time the line linking the capital to its western suburbs has seen tragedy.

In September, two commuter trains smashed into a bus, killing 11.
