The 28-year-old was accused of assault after he got into a disagreement during a house party in East London last December.
He was released on bail, but missed his Thames Magistrates Court hearing in March.
A spokesperson for Scotland Yard has confirmed: ‘A warrant was issued for his arrest.’
The Argentinian model, who is currently filming TV series Splash in Argentina, faces a maximum of six months for common assault, and could now also face three months for skipping bail.
New mum Katie Price couldn’t hide her delight when Leandro was initially arrested, tweeting:
‘Just had a phone call...someones been arrested at last his true colours are being shown.’

The 35-year-old met the father-of-one at an Oscars party in 2011, and the two were engaged for 6 months before going through a bitter split.
Katie accused Leandro of sponging off her, whilst he branded her ‘old and talentless’.
Katie- also known as a Jordan- gave birth to fourth child Jett last week, her first child with third husband Kieran Hayler.
Despite a traumatic, and reportedly premature, birth, the model has revealed she can’t wait for her fifth child.
‘We’ve been through a nightmare, but it’s made me and Kieran so much stronger and we can’t wait to have another baby’, she admitted over the weekend.
