Former BSI banker Yeo Jiawei was handed a 30-month jail sentence for tampering with witnesses involved in Singapore's investigations into 1MDB

Singapore's High Court handed a 30-month jail sentence to Yeo on obstruction of justice charges.

Yeo was accused of tampering with witnesses who were crucial to Singapore's investigation into money-laundering charges related to 1MDB.

According to Singapore's Channel News Asia, the court heard how Yeo urged three witnesses to lie to investigators and destroy evidence that would incriminate him.

The court also heard that Yeo enjoyed close ties with Malaysian businessman Jho Low. Yeo was said to have stayed overnight at Low's apartment and had been on the latter's private jet at least three times.

Yeo faces several other charges - from forgery to money-laundering - related to his dealings with Low. The court heard that it was Yeo who brought Low to BSI as a client. The other trials will begin in April.

According to Reuters, Yeo's lawyer Philip Fong said Yeo was "seriously considering appealing the conviction and sentence".

He is the third BSI banker to be jailed under Singapore's investigations into the 1MDB money trail.

Yak Yew Chee is now serving an 18-week jail term on forgery charges and failure to disclose suspicious transactions.

Last Friday, Yak's subordinate Yvonne Seah pleaded guilty to similar charges and was handed a two-week jail sentence.
