Denis Cremona, 35 and John and his wife Maruska Mamo, 26 and 28, respectively, have been jailed for a year after they admitted to trying to steal the handbag from a Japanese tourist in St Julians.
Mr Cremona also admitted to relapsing.
Magistrate Edwina Grima considered their requests to join a drug rehabilitation programme and the fact that they had committed a similar crime within days of this crime.
