Police in Argentina are hunting a family-of-six who crammed onto one motorbike before riding through the streets without helmets. They were spotted driving through the city of San Miguel de Tucuman in Argentina's north-western province of Tucuman. A man was pictured holding the handlebars of the bike while three young children straddled the petrol tank in front of him and a girl and a woman sat on the seat behind him. People carrier: Two adults and four children were pictured riding on the same motorbike in San Miguel de Tucuman, Argentina . It comes just weeks after a similar  pictured emerged of a family of seven riding on the same motorbike though the city of Junin in Argentina's eastern province of Buenos Aires. Describing the most recent case, passer-by Etel Ramirez Nazario, 46, said: 'It was shocking to see. 'Three little children who couldn't be more than three or four were all at the front, the dad was behind them. 'Behind him was another child who I'd say was about seven or eight and then the mum on the back. 'They were going pretty fast and none of them had helmets. I dread to think what would have happened if they had hit another car or fallen off.' Police are also hunting a family of seven seen riding on the same motorbike through the city of Junin just weeks ago . The family's actions were condemned on social media sites after pictures of the incident appeared online in Argentina. One user, Amatista Avalos Muro, wrote: 'This is absolutely unbelievable. These parents are setting their kids up for death.' Another, Ramses Crespo Cruz, posted: 'So sad that some parents are so irresponsible. Those poor children.' Police say they are looking for the parents. A spokesman said: 'We have seen the picture and strongly condemn this utterly irresponsible and dangerous behaviour. 'We have appealed for anyone who recognises the family to come forward.'
