A former school cricket coach was jailed for 15 months on Thursday for helping two assistant coaches, both sisters, to commit housebreaking and theft of $20,392 worth of property.

Jeraj Puvaneshen, 27, was a full-time coach of St Andrew's Secondary and St Andrew's Junior College when he abetted Rajeswari Pasupathy, 26, and Vigineswari Pasupathy, 23, to burgle a flat in Hougang on May 17 last year.

The case against the two sisters who have represented Singapore cricket is pending.

A district court heard that before the cricket training began that day, Rajeswari came to know that the 12-year-old victim's father was away and the boy was staying alone.

The two women then told Puvaneshen of their plan to steal whatever they could from the victim's home.

While Puvaneshen took the boys, including the victim, for a jog outside the school in Francis Thomas Drive, Rajeswari and her sister took the house keys from the victim's school bag and went to his home to steal valuables. They took a cab back to the school and replaced the house keys into the boy's bag.

Subsequently, Puvaneshen, together with the sisters, sold the stolen jewellery for $4,080 at a second-hand shop in Serangoon North Avenue 1.

Eleven days later, Puvaneshen took some of the stolen jewels belonging to the victim's father from Jajeswari and sold them for $1,180.

He was arrested on May 31 while on his way to sell the stolen camera gear found in his possession;.

Puvaneshen also admitted to helping to dispose of $10,239 worth of stolen jewellery. Two other similar charges were considered during his sentencing.
